The only request I have is to -please- consider recording this and posting it on youtube or something. I’d love to see it but can’t make it to Ireland anytime soon.

In particular, things you’ve had to do to WPMU to handle server load (tweaks from the base WP MU code), etc would be very interesting. It seems documentation on it is a little slim, and I know a lot of people have problems when they get to greater than 32000 blogs/users.
