What good would a 4-port 10/100 nic be?

[pX]

I just acquired one for free basically. I don't see any other uses for it other than for a router. Is there any thing else it could be used for?

basically im trying to decide if i could possibly use it, or if i should sell the thing

webserver...
or if you have a switch that can handle it, do bandwidth agregation(sp?) ie: 400 mbits max connection between your machine and the switch...

even better... FIREWALL
