Thanks, I'll take you up on that offer.

The application I'm interested in is a small version of "PacketFence" 
www.packetfence.org, on a commodity router, for deployment internally in 
our network for network control.  In particular, I intend to use ARP 
spoofing to isolate internal miscreant systems.  I could write the app 
in C, but I expect lua will provide a quick proof of concept, and likely 
adequate performance for production, at a savings in programming time. 
The original app requires perl, mysql, etc. - way more than I can put on 
the box, and way more functionality than I want anyway.....
