PC Wifi card hacking?

I've recently had a few questions and comments sent to my site about different airport issues, so I'm doing a write up about what do to. Anyway, I was wondering if anyone knows of anyone or has tried yourself any unconvetional ways to get your mac on a wireless connection. ie. a weird airport card replacement? or anything besides just a USB device or a ethernet bridge...

thanks.

(or any good sites about this)
