Xbox Wireless Apapter Connections

Before I try and actually try it, I would like to know if
the Xbox Wireless Adapter can support two connections at
once. I already have it connected to my computer, but I
also want to connect another Xbox to it wirelessly with ad
hoc system linking (using a second wireless adapter, of
course). Can I go ahead and do wireless system link
immediately without affecting my computer connection, or
would I have to abandon my adaptor-computer connection if
I want to do wireless system link?
