I still don't quite understand the first problem...  Will investigate a 
little though

Yeah, give up on that one I think... Or at least make sure your echo 
canceller has a really good training algorithm... I think the drift will 
be far too rapid to get good echo cancellation to be honest...  I 
suspect that clock drift will have a very bad effect on the echo 
cancellation algorithm (think of all the filter taps moving left a 
couple of taps every few seconds... nightmare...)
