Opera Unites Web Browser and Services

by alec on June 16, 2009

Opera Unite launched overnight.  A browser with a built-in web server, and some services like file, photo and media sharing, chat, and a web server, Unite is touted as a game changing “reinvention” of the web.  The idea is that instead of uploading your photos to Flickr to share, for example, you’ll simply send the URL for your local PC to friends and family, and they’ll be able to view your photos directly.

Opera Unite is straightforward to set up.  Simply visit Opera Labs, download the appropriate build, and run the setup program.  Once installed, it’s straightforward to run services as well.  Open Opera, press the “Panels” button on the top left side, and then choose the Opera Unite tab about half way down.  At that point, you can start up any service you like, and start sharing your content.

It’s pretty foolproof.  Opera Unite knows about UPnP, so if you have any recent model router, it has no trouble punching through firewalls.  Plus, the URL it creates is pretty easy for users as well.   For example, my photos are located at http://quad.asaunders.operaunite.com/photo_sharing/.  I dropped some snaps taken over the weekend at the Medieval Festival in there. My “Fridge” (something like a Facebook “Wall”) is located at http://quad.asaunders.operaunite.com/fridge/.  Try it if you’d like.  Drop by and leave me a note. 

Opera have done a good job.  Any dummy can set up and run a local server and services.  Embedding a server inside the browser is a great benefit for web developers. They may just flock to this, because it’s a whole lot simpler than setting up a real web server.  It certainly will be a quick way to share a file or two as well, if you happen to have Opera installed on your PC. 

As much as the Opera team might wish otherwise, however, Opera Unite is not a “revolutionary new technology” that will “reinvent the web” by “democratizing the cloud”. Why? The vast majority of PC users do things like turn PC’s off at night, or shut down browsers when they’re not using them.  I know I certainly shut down the browser. That makes the services I might offer to my friends and family using Opera Unite transient, and that is the problem with embedding the web server in the browser.  A server should properly run as a service, not as a widget in the browser. That way it’s always available so long as the PC is turned on.

Perhaps the most interesting scenarios might be the ones in Opera’s traditional stronghold – the mobile browser.  Cheap and cheerful file sharing, photo sharing and media sharing tools have never been done well in this environment.  And imagine the potential social networking scenarios possible with a portable “wall” or “fridge” in an environment like a bar. 

Your comments welcome.

P.S. Kudos to the Opera PR team.  Whoever came up with that gem “democratizing the cloud” deserves a pat on the back.

Does Peer-to-Peer (P2P) SIP represent the future of SIP communication? Does it have the possibility to enable the creation of a peer-to-peer communication cloud that could rival Skype but be based on open standards? Where would P2P SIP fit? In an enterprise environment? consumer? What’s the technology behind it all, anyway?

Today’s Squawk Box was a fascinating one for those of us interested in the network level of how VoIP can all work. Today, pretty much all SIP-based telephony is “server-centric”. You have SIP servers to which SIP clients register. The SIP servers, be they IP-PBXs, call managers, whatever… control the overall conversation. But what if you could have SIP in a *serverless* environment? What if SIP endpoints could “self-organize” and create P2P clouds? How would this work? How secure would it be? Who would use it?

Our guest on the call was David Bryan, co-chair of the IETF’s P2PSIP Working Group and also CEO of SIPpeerior Technologies. We dove into all of those questions mentioned above and many more. It was quite an enjoyable and interesting call and we hope you find it helpful to understand this potential new way of organizing SIP communication.

TerraNet's P2P mobile play

September 11, 2007

Swedish company TerraNet has announced a technology that allows peer-to-peer calling between cell phones.  The phones search out other phones within a kilometer radius, and make the calls directly, phone to phone, bypassing the base station.  One intermediate phone could apparently be used to relay a call to another phone out of range.  Think Skype, [...]

Ooma? Oh my…

July 19, 2007

People have been pinging me all morning about Ooma, the new hardware based peer-to-peer VoIP solution that was announced today.  Caveat: I haven't yet used the product, or talked with the founders, so folks like Walt Mossberg, Om Malik, and Michael Arrington have an advantage over me.  Ooma is a line of innovative new hardware products [...]
