As I understand it, these French villages are huge money sinks. You buy them, then find that French law requires you maintain them in their original condition. You can't bulldoze them and build modern buildings, and making 15th century French hamlets livable (let alone suitable as a hacker-space) isn't easy.
If you love restoring old buildings, knock yourself out; but otherwise I'd be very careful. Check what the impact of heritage laws is.
