ag 2.3 capability negotiation -- when?

[Susanne Lefvert]

Hello Stuart,

I agree, the ideal design would allow clients to do capability-matching on 
the fly.  This could probably be done by adding an additional method to 
the venue SOAP interface that would let clients negotiate capabilites 
separate from the venue enter operation.  My plan is to first implement 
the simpler version of the design, that would require participants to 
disconnect and reconnect before any changes take place, and then extend 
it to be more flexible.   

Thank you very much for your comments.
