I have xampp (portable edition) installed on a flash drive and also an external harddrive. That way you can put it into any computer and view your site.
The only thing you need to watch is that the drive name stays constant across computers. If you install it, and it is 'E:', then put it into another computer where it is 'D:' it seems to cause problems.

Doesn't really answer your question, but might be another option.
