Could you please elaborate on this? Why is Coin not a nice proposal for 
a Jingle client?

I think that all those points are way too much to call it a protocol. I 
also don't expect a mobile phone to implement a fully capable focus, but 
it should be able to join a conference. How would you handle this?

Implementing two protocols would be a pain, but I don't see how they can 
be combined, they seem pretty orthogonal to me.
