Re: [Ekiga-list] A comparison ALSA-PULSE (long, addendum)

Hi!

I'm a newbie here, and shouldn't really answer... but since nobody else 
does, I can share my thoughts. Which basically are that this looks fine, 
the Ekiga people focus on  enhancing the alsa driver, you handle the new 
pulse plugin which obviously is needed. But let's hope someone of the 
elderly let us know what they think.

I presume you already have thought of this, but just in case... a few 
things I  think would be nice in a new plugin interface:

- Event-driven model with callbacks matching e. g., pulse as an alternative
- A mechanism  to retrieve statistics  in a generic way from the connection.
