HI Ken
Yes, I do have a VM machine built on Debian Squeeze which I use for testing. Trouble is, that the image files are so large.
I know from my own case a few years ago, that getting going sometimes means a sole teacher showing what Moodle 'can do' before a school will actually sanction an installation. The VM solution would allow such teachers to get up and running on a personal computer and also allow access from other networked PCs, thereby winning colleagues over without the technical hurdles. The transfer from experimental sole XAMMP or the like to running network server also pops up here in forum problems quite often!
I could host an image on my http://manxman.ch site but it's performance is not particularly fast, as I only host language learning tools there.
Let's see if others are interested. I'd probably like to post up a Server containing my Moodle Language Teaching Tools 'ready setup' in any case.
Regards
Alan
