I've had problems with the networking on Parallels on my Mac Pro (3GB.) My Mac Pro, since there is no airport solution yet, is using a Linksys "game adapter" wireless thingy which is 10-Base-T. Not sure if that is relevant. The symptom is that network seems to "hang." Any large download, file operation or other piece of network work dies. I am using the Parallels driver from the tools, and I've also tried the other Realtek driver. Is anyone else experiencing this?
