I don't control the whole server .. I used to be able to look at the contents of /usr/home but I can see that loophole has been closed. All I can fiddle with is my slice of the host.

I did consider hosting this myself, but I'd rather have it somewhere it's always available, rather than somewhere a little more convenient. Part of this exercise is the implementation story. :)

Update: However, now that I'm thinking about it, I might also add a link to something hosted locally that takes advantage of different technologies such as the ones your link points to. Serving up a Mojo add using CGI is a bit like having a mountain bike stuck in bottom gear. it works, but you're missing a lot of the experience.
