That seems like a fine plan for now. I assume you set the exposure now
to go as faint as possible. For short-period variables (e.g. W UMa's
and RR Lyr's) we might want to explore the tradeoff between faintness
and time resolution). It might make for an interesting experiment to
image a field with a known eclipser and see how well it works out. I
can do the leg work to find an appropriate candidate.

It sounds like people are actively working on control software and the
data processing pipeline. I guess what we'll need next is something to
analyze large numbers of light curves to classify the variables. The
ROTSE and MACHO guys seem to have that done reasonably well and I
suspect we could get their code. If not, I'll write it. As far as the
analysis of eclipsing systems, that's my bread and butter. I've got a
proposal in to NASA's Applied Information Systems program to build
software that (a) does full light curves of star-planet binaries (not
just the transit) and (b) makes it easier to analyze binary star light
curves. (a) isn't so important here, but (b) would certainly see use on
TASS data.
