I realize I'm responding to this way late, but I was following the 
discussion on the linux kernel list when they were debating the change 
of the default from 1000Hz to 250Hz.  The biggest outcry against the 
change were from a lot of the multimedia people, who complained that a 
lot of sound and multimedia stuff, midi, etc., would suffer greatly from 
a slower tickrate.  I'd imagine a lot of the codecs that asterisk uses 
would have the same issue.
