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.

Is it supported to do the job of pygments in Lua?

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

I know... bandwidth and server compute time.

Also there's no reason (other than not enough care taken with frees atm) 
cgit should only be buildable as a cgi starting up its own process each 
time.

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 
save us both a lot of time by just saying it now, and I'll stop trying 
to sell it here.
