Hi all, I've placed copies of my paper on implementing AG functionality over the Jabber/XMPP protocol online here:
http://people.vislab.usyd.edu.au/~ssmith/apac05/ The crux of the paper/presentation is that all the functionality associated with the current AG can be replicated over the Jabber protocol with little or no modification. In addition some other useful properties fall-out, including the possibility of P2P ('venue-less') AG sessions and more advanced shared-application interaction. The Latex source for these is also available via Subversion: svn co svn://projects.vislab.usyd.edu.au/apac05 Also there is the presentation on using Sawfish for advanced window management under Linux. Cheers, Steve
