Regression testing with binaries is a pleasure: it takes only a few seconds :-) on each bisection. I bisected a 16 step regression in just 20 minutes, and most of that time was spent running the application and dealing with 2 X-server crashes.

I already love it.

Maybe Git can compress it further? The other idea I had is that users should be able to regression test through a GUI tool. Maybe the GUI tool can just download and run the +/- 122 MB binary snapshots for specific commits, instead of having the entire binary repository locally?

tried compressing the .git directory. or maybe "git gc" can help

If the tool is not too big and is textual, why not
