I don't believe you're doing more than stopping the weak and infirm
at this point. I don't know of an IM that doesn't work on http, for
example. You might be stopping some services, like real-time ICQ chat
and file transfer, but that's probably it. That assumes you're let-
ting the user on the net at all, natch.
