Can PCs Control a Mac via Remote Desktop?

[John B.]

Wouldn't a proxy server, firewall, or other network security device be much more transparent? I have these scary visions of 15 "not very computer-savvy people" yelling across the office "who's on the Internet" while waiting to use a remote desktop client to run a generations-old browser. I love my Macs as much as the next person, but waiting on a remote client to run Mac IE 5.2 would make me scream.
