To the JumpBox guy.
Interesting idea.
You need to come right out with what you're doing, on the home page, or in the first sentence of the 'about' page. I don't want to read a paragraph of crap about automobiles, before coming to what you're all about.
Also, I'm sure LAMP components (ie the various tiers of web server) would be a hit - ie seperate VM images for apache, database, etc.
