Hello Frank , all

thanks for your great  effords in multicast research and testing, SAP  
is like you said a very handy tool to receive annoucements via  
videolan for example
and i can´t understand why it not beeing evolved and supported    
more . security issues  maybe?

Since i get a tunnel setup with a FREE  tunnel broker ( sixxs.net )  
and installed a "dbeacon" on leopard with some help ,  i tryed to  
discover multicast without any luck yet.

The m6bone seems not longer connected with most of the POPs from sixxs  
<http://www.sixxs.net/pops/status/>

But anyway , since i am not able to come to such a meeting it would be  
great if someone could raise this issue here.
