no. currently i'm running this show with two dvd players, two md players
and a winxp machine that runs arkaos (a cue player that would suck even
if it ran natively on linux), all piped into a video scaler
matrix and a yamaha 01v96... works nicely, but a bit bulky for my taste...

nothing against ardour, it's absolutely great. but we are talking about
situations where customers get really really pissed when things go awry
and i would hate to see a crash during a show due to a bug in a feature
i don't need - hence, i'm looking for a somewhat minimalistic solution
that will "just work" for very large values of "work".

no interactivity is required during the show except for the manual
triggering of playback on cue.

the global sync source in this scenario is a carbon-based biped (i.e.,
me). not even a timeline...

most theater installations will gladly trade hours of painful
pre-production for maximum reliability and simplicity during the show.

for productions that use it, syncing to external timecode might be
interesting, but it's not yet very common (except for driving fireworks
or other extremely complicated events with critical timing).

yes, please :)
