[labnetwork] RFID interlocks

[Iulian Codreanu]

Mike,

I am working on a system similar to Michael's. I am a little more 
"lenient" than him (I use N-3). One of the more difficult aspects of it 
is that I work under the policy that no "penalty" fees can be charged to 
grants so I am aiming for the PI's discretionary funds. That should 
generate a very strong incentive for the users to minimize the number of 
times they forget to log out of tools and swipe out of the cleanroom.
