I wrote it specifically for use in a project, but I need to clean it up=20
so that I'm not totally embarassed when I post code. ;) heh heh.=20
(Actually, it works well, but I haven't used it in a while.)

It really is cool, though. Right now it uses an embedded ruby=20
interpreter. One possible TODO I'd perhaps like to try is to use the=20
same interface, but make the backend communicate with ruby in another=20
process. (It's a long story, but the reason behind that would be to be=20
able to have multiple independant "embedded" ruby interpreters...=20
something that last time I tried to do I gave up fairly quickly after=20
seeing all the global variables!)

I'd actually almost forgotten about it. I'll dig it back up, clean it=20
up, and post more info here in a few days. (Err, unless I don't get to=20
it before I go out of town for the thanksgiving holidy here in the=20
US...) Okay, so, a few weeks. ;) I'll probably throw it on a subversion=20
server here at icecavern, but I'll put the project page on rubyforge.
