I think that - Gadget actually extends XMPP, so there are new XMPP msgs on the wire -- which means you need new code on the client side - Telepathy-Gadget - Gadget itself (which is on the server side) remembers who you've interacted with recently, so above a certain threshold it'll show those on the Network View - If you use the search on the network view, it'll also run a search against Gadget so new nodes may appear in the Network View (not just the greying out of non-matches) there are other changes as well, I think. Right now a shared activity is - on XMPP - a 'chatroom'. With Telepathy-Gadget and a Gadget server they are implemented as something custom and specific. I don't know what extra tricks you can get out of that ;-) OTOH, it stops being generic XMPP so it kind of binds you to ejabberd+Gadget (maybe other XMPP servers are supported as well?). And you can no longer interop with any random XMPP client. cheers, martin -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

I'm assuming the problem it solves is lack of partitioning, and the fact that the neighborhood view becomes kind of impossible after 50 users, etc. Right? So what does gadget do? Is there a new client side UI for electing groups? Who chooses, the kids or the teachers? etc. Daniel ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

Yes, that's what I'd suggest -- change things on the client side to generate a random string (or a hashed mac address) with the appropriate format. Maybe pre-pend it with a known prefix, as XOs have a series of known prefixes in their serial numbers. One important thing is that the client side must remember these generated serial/uuid as they are used for other stuff. > Also, how is moodle integration coming along.

Well underway -- it's working if you grab the moodle from my git repo, it doesn't require changes to registration-server, and it works with the same ejabberd we have on XS 0.5.2 . It does require a new Browse.xo -- search the list archives for discussion about the latest Browse.xo and the 'moodle authentication' patch in it. cheers, martin -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

"Client" code for Gadget seems to be integrated in the Telepathy new Sugar present on the SoaS images. The server side -- the proper gadget code -- isn't on any XS, and I haven't seen or tested it (lack of time :-( ) Even if I had, it's a ton of new code, a lot more adventurous than what we're doing w moodle. So short/midterm, following ejabberd+moodle is lower risk from the perspective of a deployment today. OTOH, if you're feeling the experimental mood, the ejabberd we have now on XS-0.5.2 is compatible with gadget.
