I absolutely understand this but it's important, from a user point of 
view, to be able to know which bits of FS are current/supported and 
which aren't.

It's useful to know that there are people using mod_openmrcp without 
issue: I did ask here if anyone was a while back, and no-one fessed up.  
I'll give it a go on a Linux box and report back.  And if you'd like a 
dev/test environment set up, then just tell me which one.

Those guys who claim to have all that money in an offshore bank account 
are lying - you don't have to reply to them in future ;-)  Seriously, 
though, I don't think it's too outrageous an idea to document what's 
supported and were you (for example) to have suggested that I get in 
touch with the contributors to the various modules, ask them what their 
view of its status is, condense the answers in to a list and report 
back, it's something I'd quite happily do.

Quite happy to participate in that, too.. the problem is that I've a 
demo to do like yesterday and the timescale for mod_unimrcp is a bit on 
the long side for that.  I'd rather not have to do it with Asterisk and 
Lumenvox..!
