Is it possible (other than using a proxy server) to force an application to use a specific NIC in Windows XP / Server 2003?

Example: I want to force FireFox to use ONLY my wireless connection while Internet Explorer uses ONLY my wired connection.

I recall there being a way of doing this at the OS level but I just can't recall it.

    Yes - you can change the interface metric of each card - so that one is more favourable than the other:
