There are 2 issues involved concerning the controller application.  
Firstly, the existing controller app was written for AG2 and,  
secondly, the reflector server location (which is hard coded into the  
app) is out of date.

I've created an updated controller shared application for AG3 and put  
it in the Data section of the Audio Reflector venue of the vv3.ap- 
accessgrid.org venue server. I've just tested it from home (no  
multicast) and it works fine although there are no built-in sounds  
available on the server.

It looks that way. Have you tried connecting via a bridge? That may  
work around a multicast problem at your end.
