An invention I’d like to see

A graphite travel guitar. I was away on business this week and I thought of actually traveling with my travel guitar. Problem is, it’s made of wood and I was somewhere very cold; extreme temp changes hurt guitars. There are carbon fiber/graphite guitars — impervious to weather and humidity (and some would say tone) — but Rainsong‘s are full-sized and the ones from Palm are too expensive. I’d think a reasonably priced, near-indestructible travel guitar would be a good idea.
