I have not tested much at all but it seems to work.
The win32 changes are now in the UCL repository. The vic from the AG cvs
compiles out of the box against the new UCL CVS directories apart from
changing common -> common/src in Makefile.in
vic seems to receive uncorrupted rtp.source.playout messages from a rat
built from CVS.
vic mbus recvd:rtp.source.playout "242b67b6" 50 from (media:audio
module:engine app:rat session:0 id:18403)
I'll look at adding the required rtp.cname messages.
