However I wonder which kind of instant messaging you are
referring to, as all the ones I've seen work fine through NAT.

Yahoo and AOL (I have never used MSN). Sure, you can do
normal chatting, but once you extend into the other
features such as file transfer, voice, and webcam...
things break.

In many enterprise environments, this would be a feature not a bug.

Maybe, but that's not the point. Not everyone who is forced to be behind a
NAT is in an enterprise environment. Plus, if enterprise environments want
to implement this "feature", firewalls work fine.

There are some webcams that are definitely inappropriate in a business
setup;

Says who? Each business is different.

given the lack of good enterprise content filtering solutions for
IM, if NAT does break IM webcams I don't have a problem with it.

You don't have a problem with it, but others do. Plus, why are firewalls
not sufficient for blocking IM?

As of file transfer, it does not bother me either as like a lot of
other network administrators I have a problem with users sharing their
office computer files with anyone unknown on the net.

Again, YOU are ok with file transfer breaking... not everyone.

For voice there's always that thing called the telephone that has the
advantage to work all the time with anybody and can be logged.

Oh, your right... so all the time that IM vendors invested in implementing
voice chat was truly a waste, because there is absolutely NO demand for
it. And all those users that currently are using voice chat as we
speak/type have simply missed the fact that they could pick up the phone
to pay more for their conversation.

(As I finish this reply, I realize it was a waste of my time... but now
that it's written, I'll send it anyway.)
