Hi Adam

Very sorry for the delay in responding, I am waayy behind on my AG mail.

It is a hard problem. And, unfortunately, one I have had 3 students working on all this year already, they will finish in a few weeks time and we will release the code to the community then. The last test I saw it was working nicely - just crashed occassionally (only when demoing to their supervisor, or so they claim :-))

We might need to discuss if you want to work on that code base and enhance it, to avoid you reinventing a rather large wheel. Or if there are other aspects you could tackle that we haven't looked at yet. One example would be T.120 - which is another hard problem (probably harder, since there is no real T.120-like service in the AG as yet, but mimicked by various approaches).

Our current code allows H.323 devices to dial into a service somewhere and pick up one of a selection of display layouts. Like an MCU it has different layout options, with a background mechanism to map different AG video streams into different positions of the display and control their behaviour on the display.

There's a bunch of things the students didn't finish though, or that we took out of scope, that we could pass around as a project. If you like, you and I and your supervisor could perhaps discuss in email (or a phone call, if we can find a common time).

Conversely, there are a bunch of other problem areas in the AG that would be great projects to work on. Ivan and the gang have a wishlist somewhere I'm sure, and if they don't I do :-)
