Yeah, that'd be great hardware to select. 

What I was thinking is that this thread seems to be driven by those of
a software bent. For that group perhaps there's an opportunity to write
code for something like a snom 820. It's a solid solid hardware basis
for the project. Snom would be foolish not to sell it for such use,
even price it attractively. That way the hardware work would be done,
and the software geeks could work their magic.
