Chris,

This really sounds like a network problem not a VServer issue. Without 
more information, I would guess that they are using a switch and not a 
hub. If this is the case, I bet that it has something to do with the 
Macs ethernet nic and the switch renegotiating the speed and duplex on 
the link. If it is a managed switch, have them lock both ends at that 
same speed and duplex. If it is an unmanaged switch, have them set the 
Macs to auto, or try both full and half and see if one works better 
than the other. Also, it could be cabling.

Anyway, without any more information it is hard to say for sure, but I 
would suggest checking the network layer first. I have seen similar 
behavior in environments like you describe, and it never had anything 
to do with the applications.

HTH,
Kevin
