This is not about software logic, it's about legal issues and we can't take that discussion here, it's for
Digium to make by themselves and we just have to respect their decision, whatever we think
about it.

We can create a community distribution based on GPL and we in the community can
encourage as many as possible to use it - but it's their decision about the type of legal
risc they consider it to be.

Hopefully the issues that stop Digium from supporting it today will diminish so that
Opus and VP8 can be included in the "official" distribution at some point - and then
everything should be ready for some fast action.

Digium has done everything they can for Asterisk - and more. 
This time it's the community that has to prove that we can handle the situation ;-)
