Sharing Internet Between 2 NICs? Possible?

[Guest]

So, I have an Ethernet card that is hooked up to a cable connection and I
have a USB WiFi Adapter...Is it possible to have them on at the same time and
can I designate which programs use what connection? Is this even possible...?
I've tried the 'Network Bridge' and that's not what I'm after.

Nope, only one can be the default gateway.

Could you not plug both machines into a router? My router has 4 sockets
for network connections.
