I am going to see if I can do something like that.

Yeah just guess why we BOLT the units into the trunk. And of course 
laptop's are a no-go cause if we would put those in about 3 month later 
50% would be on ebay.

Wifi is fine but might be painfull timewise.
using just the 128bit wep encryption will be fine. The system that we 
are using right now is just a "Norton Ghost" server and an access point. 
Not connected to anything else.

The only data that could be sniffed in the case somebody breaks the wep 
key is just a standard OS installation. No passwords or anything 
sensitive. Right now all the units do is CAD and NCIC/WALS lookups. And 
for NCIC/WALS lookups every cop has it's own encryption key that changes 
every 90 days and is not stored on the computer.

I guess for the "big" install we will go with 10/100 wired stuff but for 
the small "drive in, i broke my computer again" fixes wifi probably.
