Tubes and Planets
Daf blogged earlier about some of the work we’ve done thus far for the One Laptop Per Child project. Tubes (although the picture looks more like snakes if you ask me :D) are a really cool technology which should let the OLPC activity authors just work on their activity, and use D-Bus and Telepathy to take care of the communications.
At the moment our implementation for Gabble (Telepathy’s XMPP backend) is pretty rudimentary and sends all data via the server, but this already lets us layer multi-user tubes over XMPP multi-user chat rooms and have it act like a bus where each member of the room is also a D-Bus endpoint. You can export objects, call methods and emit signals just as normal.
Next up we’re going to implement them in Salut (the link-local XMPP backend, which we’ll use for communications over OLPC’s mesh networking) using good old TCP for the one-to-one connections, and some of Sjoerd’s more exciting link-local multicast stuff for multi-user tubes. To make tubes work for desktop clients we’re going to go on and look at more advanced Jingle-based ICE NAT traversal stuff.
Maybe one of our next ports of call should be raw stream tubes for existing TCP protocols, then we can make a reality from X over Jabber (or whatever other protocol) that Matthew Allum was wondering about. 🙂
I’ve also just stolen Planet Collabora from Daf’s home directory and put it on its own subdomain, so you can add it to your feed readers and keep track of what we’re up to with Telepathy, Farsight and friends.

Hey!
This is really cool….
I have some questions regarding these tubes…
1. I am planning to work on a project something based on VNC for Remote desktop/Assistance using stream tubes… Can you guide me with some links to api’s and tutorials…
2. Does it provide Security ie., encryption
