ASAS-3 is fine work, but it still only samples (at best) once per day. How will this definitively answer the question of flaring in Miras? If the flares lasted days, they would already be known phenomena; if they last only a few hours, sampling </=1x/day won't help -- much. TASS Mark 4-style observations, observing a field many times a night, would do the trick, but TASS does not return to the same field every night. You can observe lots of sky once a night, or you can observe a little of the sky a lot. Can't do both without a whole lot more money than there is out there for this type of project. And you can't answer the question of short-lived phenomena in Miras without watching a whole bunch of them at fine temporal resolution. That is a tough nut to crack.
