What operating system are you running the AGTK on?  It may be worth
searching for an alternative version of rat (e.g. the default UCL version)
to plug in instead; I ran into problems recently with rat on both Win
XP and debian.  For Windows, I was able to plug in rat from AG2.1.2,
and for debian it just took rebuilding rat from source (from my vague
recollection of it all).  It's contained in the source distribution on
the AGTK download website.

Do you have multicast connectivity?  If you have a windows machine
available, you can test this using Internet2 Detective

If you don't have multicast connectivity, you'll have to look for
unicast-bridged venues (e.g. the Test room on the ANL Venue Server;
to use the bridge, you need to select Preferences/Use Unicast)
