[CoLoCo] Multiple Network Interfaces, one card?

[Ringo Kamens]

I have a problem I think somebody here may have enough expertise to
solve. I have one wireless card and one ethernet card. What I want to
do is set up two separate network interfaces so that I can have my
wireless card send data from two separate MAC and IP addresses. Is
this possible? Yes, I googled it and the results came up empty. I
would appreciate any help I could get.
Thanks,
