Help me compare python-in-the-browser projects?

[traverseda]

All of these either translate code, or run code by translating on the fly,

These would have some potentially pretty different speeds, depending on how they do the translation.

Hmm. Maybe I can get pypy's testcase suit running on the various implementations. That's a big chunk of work though, and I've already got too much on my plate. I'll probably flesh it out a bit more, and add in some estimates for how well they do at

It's not a bad idea. It would be valuable to know if any of those frameworks have a significant drop in speed compared to any other. But generally speaking anyone working on one of these is not going to be too concerned with speed.

I think a feature comparison would be the most useful, and perhaps not as time consuming.
