No. This can't be a dedicated-task system. Also, the app uses things
like cron and sendmail to exchange survey data with a satellite - which
unfortunately needs to be done via email.

I was just using slocate as an example to give people an idea of what
I'm up against without having to describe the entire app.

Last winter we tried using an intermediary system to handle the
satellite, but whenever the satellite connection glitched, things got
out of sync. And the data sets are too large to transfer over an 802.11b
connection before the merged survey data underruns the visuals.
