I think I already stated my intentions in another response, but it's summed 
up with: I just want to connect one notebook.

The situation, and why I wante a bridge:
1) My Wireless is dead as a doornail. I will very likely need wireless in 
2-3 weeks.
2) I will also need the notebook for most of this time - I can't send it out 
for repairs.
3) I don't want to get a USB or PC Card wireless adaptor since I will 
occasionally use FreeBSD and/or Linux, and I've yet to have any luck getting 
wireless set up in either. And since I use FreeBSD a lot more than Linux, 
getting it to work in just Linux won't help me a lot.
4) I went for a DD-WRT'ed router because it was about $50 cheaper than going 
for an actual bridge.

Anyway, as I stated, I'll be looking at the TOS to verify that what I want 
to do won't violate it.
