I looked at it, but there's no md5 api in JS... you have to do it by 
hand in JS.  It's possible but I think it might be slow if it hits a 
page of 50 different email addresses.

What it does today is spawn the python runtime, start that up etc.

It could optionally link against OpenSSL then :-)  It can optionally 
link against lua.

If you're not interested in going where this stuff is going, you can
