Hi Simon,
Where Can we see the video patches you talk about? I´m very interested.
I'm very busy till the weekend, I'll gather them up and post them after that. I'll give a URL to the list when I've done it.
and yes - it isn't a perfect solution, there will be some jitter due to the LAN so it isn't as nice as proper time syncing would be, but since the frame-rate is usually 40ms that jitter is impossible to notice in almost all circumstances, and since actual frame-numbers are sent then there is no slippage or getting out of sync over time. I've used it with 5-projector wide images with fast movement across them.
The biggest challenge is always getting the codec right for the circumstances, issues like whether the original was interlaced can be tricky. I find the results always better than DVDs which where often the more expensive alternative.
The system has been especially useful to me when I've needed to present a sequence with different formats, possibly with still images, when I've wanted to be able to cue things manually, and when lots of keystoning or colour correction was needed to line things up.
