I think the overlooked market is india. Recently the indians have been getting very upset with microsoft and are moving towards OSS. This is because MS has decided that it no longer needs piracy and is properly trying to clamp down. This has left the indian sellers rather unhappy, and they'd be more than happy to peddle linux instead.

I'd guess the government moving is due to the need to remove vendor-lock in...
