HIPA and Network Configs

I remember months back some members of PLUG talking about HIPA regulations and
things like hospitals having to be compliant due to the need for privacy and
security of patient medical records.

The company I now work for is still in the ramp-up phase and will be doing
medical research and so there is some concern about how we can setup our network
to link the various lab spaces that have been donated to us.

The concerns are with allowing 802.11 wireless access to our network and using
Wireless bridges to link up some labs that are near each other. Does anyone
have any advice/pointers that could help?
