The IT manager at my client feels like it's a security risk to have
anything but the webserver in the DMZ, and that's his *only* concern.
I'm not even certain it's a valid concern.

Well, it's actually my client who wants to get Enterprise, but they
still want to know what the benefits are. So do you think that 300 to
500 users is enough to justify clustering?

That would be cool. We're using VMWare for email servers at some of our
other client's, and that's pretty slick stuff.
Also what about coding in Enterprise? Any differences, or changes in
technique necessary to take advantage of clustering or anything else
nifty that Enterprise offers?
Thanks,
