Daveny, I can't speak for the OP, by my experience is that directors often change the timeline, leave things blank, chop and swop etc - nothing is set in stone till the deadine. Sonar single-clip policy has been a source of annoyance for me on more than one occasion as well.
The MTC thing sound like a great idea and I have thought of trying it many times, but I have never had a real hard core reason to try it. I think if I scored a long movie and needed wall to wall music I might try this. i don't like working in larger than 10-15 min video chunks in Sonar
As far as directors changing timelines, blank areas etc... Yes this happens to me every week. I just plop the changes into Vegas and then go to work on the audio in Sonar. I usually look really good to the producers 'cause they know they can throw anything at me, I don't complain, I turn around and even on a bad day, give them a decent sounding track. Some of them can't figure how I do it, how I can get a hit to happen in the right spot when they sent me elements on different days and different pic references. It is because i can do a little video editing and I have a ton of experience and a solid working template in both vegas and Sonar.
The idea of having multiple Video tracks and timelines in Sonar seems to me to be a recipe for disaster and asking for sync issues. I can't seem to wrap my head around how that would work. Maybe I'm just too simple minded.
So would you have the timeline solid in Sonar and you could move multiple videos back and forth? When you moved the video would everything in Sonar follow it including audio, midi and tempo maps? how does that work?
SO back to the OP...sorry 'bout the hijack..I'd suggest trying to sync thru MTC. That should be pretty easy to do thru midi cables if both computers have midi cards. If not a router with a midi app should work. I use to do this with GigaStudio on another computer. It was a little PITA cause if you'd have to reboot anything you had to resync everything.
I'd still suggest working with smaller picture chunks on one computer. Put Vegas to work here.
