Yeah, when I was writing that I was just kinda hacking something together to see if it was possible and it ended up working so well that I pushed it out. Probably could still use a bit of polish yet.
Would anyone be interested in a write-up of how I put it together? It might finally be something to post to one of the umpteen blogs I've setup and never used.
I'd definitely be interested. :)
