While it's not ideal and can be noticeable, it's not as bad as all that.  I 
regularly speak with people in Australia which  is over 400 ms ping time 
away, and while we occasionally talk over each other, it really doesn't 
impact much at all.  I'd imagine it could be a problem if you made it much 
bigger though.
