if they have to be exactly in Sync, i would recommend networking the machines together and using Michel's SyncVideo actor. you could then trigger them at any time.
I was curious if anyone out there in Izzy-land had some neat tips or tricks for working with these patches, or if there was interest in an in-depth tutorial or report on how the system works (including show files).
Any chance you still have those files? If so, I'd love to have them.
