PyPy allows *true* sandboxing, as does IronPython through AppDomains.
I wouldn't recommend either for 'in the browser' use though.

You can do client side programming in the browser with Silverlight.
It's great fun to program, and very flexible, but limited to Safari,
IE & Firefox on Mac and Windows. Moonlight is making good progress
which will bring Silverlight to Firefox on Linux - and eventually more
browsers and platforms.
