Now that this software has started to stabilize, I've been shopping around for a good web hosting providor to run it on. After a lot of comparison shopping it looks like dreamhost.com is the place.  ssh, imap, php5, phpmyadmin, unlimited domains. It's got everything I need. Nobody else did - all of them falling short in one aspect or another. If you find something not working over the next few weeks, it might be because the bits are all being packed in boxes and shipped elsewhere.

Of couse it might also be that it's just plain broken.
