This is a really great tool. I use FreeBSD most of the time, but switching back to WinXP is inevitable (for games, and some Windows-only programs -_-'). This makes getting files from that partition much easier.
One thing I would love to see added (other than write ability, but that isn't even working in Linux yet :P) is the ability to mount to a drive letter other than X:\. Perhaps giving the user a list of the unassigned drive letters currently available and allowing the user to select one?
Great progress on this, though. I may download the source and see if I can contribute (this may be beyond my level of expertise, though . . . only been using FreeBSD for about a month XD).
