Ripped nearly 3m of 44m oak over the weekend.
TS55, panther blade (for rip cuts) and it worked a treat. Basically the same as the images above. Just make sure you use clamps and have some scrap. I find that clamping another board at each end can help too, to create a "wedge" so to speak. This was all in one pass, no problem.
The only downside with this setup compared to cross cutting with my MFT is the time to setup/align the boards. If this was repeat cuts it's not as fast as cross cutting. I will invest in the benchdog.co.uk parallel guide to help here. If this was wider cuts (wider than the track) then the use of a temporary flagstop is fine though, it's just for smaller rips that it takes some setup.
I don't have a table saw yet. I will at some point I'm sure - for the speed and ease of cuts that are smaller than the rail - but as it stands my MFT/tracksaw combo is giving me everything I need. It seems odd, but I feel a heck of a lot safer ripping the above by bringing the tool to the piece, than the other way around. I'd stand by this statement even for small rips too.
