I've always thought that a 802.11b interface with a directional antenna 
on a singleboard computer like those from Soekris might not be a bad 
solution for this kind of thing.  It requires a fair amount of software 
fooling around though, to get it working and doing something useful. 
The off the shelf wireless data link boxes are more useful for that 
reason.. basically they're like a remote relay so you can drop them into 
an existing system.
