Hi Raffa! I don't think JACK will be terribly useful here as it is only supported by LiVES which is lacking in compositing features, all the rest of the Linux NLE's don't support JACK (yet). Xjadeo is a video player that uses JACK and will sync with JACK transport, I don't know if you can run multiple instances of Xjadeo to a common output though...
I'm a little lost with answers for the actual compositing, I do know that Openshot can quite easily route 4 distinct Video tracks to one screen by mapping them each display in 1/4 of the screen, but I think you are talking about something other than that. One thing I do know is that recent GIT builds of Kdenlive 0.9.3 have a great audio alignment feature for exactly the kind of thing you are talking about. I used it for a music video recently and you simply select one track to be the audio reference and you select the other tracks to align themselves with the 'reference' track and it works great and saves a huge amount of synchronizing headaches. I am pretty new to Kdenlive and I'm not terribly sure what the compositing options are with MLT (it's underlying framework.) For Ubuntu users there is a Kdenlive-SVN PPA here: https://launchpad.net/~sunab/+archive/kdenlive-svn Good luck with your project, I'd love to see it when it's finished!
