Anyone tell me what the law or FCC regs are on power limits for wifi client adapters? Is RF Output 4W (36dBm) (including antenna gain) legal? Are these regs enforced?

It's different for PTP (point to point) and PTMP (point to multipoint). If your client adapter is talking to an access point or wireless router, it's doing PTMP. There are also some difference between the 900, 2400, and 5700MHz bands.
Enforcement by the FCC, not much.
The FCC will act on complaints to licensed services and against manufacturers that sell uncertified or overpowered equipment. They don't have the resources to chase individuals. However, if you deploy an overpowered radio in my back yard, I'm going to organize a transmitter hunt, with the grand prize being your transmitter. Also, search this newsgroup for the term "alligator".
