Yep.
 More evidence of the statement I made in a previous email.
Even us computer experts disagree on the correct interpretation of the 
LGPL. What will the courts decide ?

In fact, with the release of chan_woomera, the license of openh323 ceases 
to be an issue. With chan_woomera, there is no linking of the openh323 
code with asterisk. Instead, all data passes over sockets to connect the 
woomera and asterisk process. 

   Further, this will compile real fast - the woomerea/openh323 
combination is compiled just once, and runs as a separate h323 daemon.
