I'm brand new to MIDAS, and C system programming in general, so please be
gentle. I've compiled and installed MIDAS 2.3.0 on Ubuntu 10.04 LTS. I've built

At DANCE we have a similar issue. We are still doing "software
handshaking" between multiple frontends (15 which read data, and 16th

At Los Alamos, we have 15+1 frontends - the 15 between them read about 2 or 3

computer. The 16th frontend handles deadtime issues and scalers (small data rate).
