Thanks to the responsers. Unfortuately, no real consensus came out.
Here's the rerun of the question:

>From the responses, it would appear that people (a) have not really
checked on how quotas impact their systems, or (b) assumed quotas were
bad and implemented scripts to be "disk police". No one had strong
claims any which way; the folks that used quotas said the performance hit
was "slight" or "not very bad".
One bit of advice that came out was only use quotas where you need them
-- i.e., on user space.
So I suppose we'll just try 'em and find out.
