I once did something similar, although I just went with 100Mbit between the two hosts, that was more than adequate formy purposes. > I was looking to gigabit ethernet first, as I figured it would be the > cheapest. > But a sysadmin I know said he wasn't sure but he thought about $4,000 > for two cards and a switch. What do you want a switch for?

Transfer-rate all depends on the hardware.. I've been able to get 800KB/s between 2 10Mbit cards and around 7MB/s between 2 100Mbit cards, and that wasn't even state of the art hardware. -- Thomas Eibner <http://thomas.eibner.dk/> DnsZone <http://dnszone.org/> mod_pointer <http://stderr.net/mod_pointer>
