That's awkward as hell. It's sad that their offering is the only decent one out there (for my needs and with that UX) that's at least got open source options. I hope VirtualPC from Microsoft becomes cross-platform and open sourced, or at least some sort of new VM software from Microsoft, since they seem to be doing a better job at offering up MIT licensed projects lately.
I wouldn't even mind shelling out $50 for a license if I needed one, but they won't let me. It takes $5000, because they require a purchase of 100 or more at a time. It feels like they don't want to spend time on small stuff, and really don't care.
