Actually, from what I've read a huge amount of work has been done on multitouch drivers for linux. We use a few different types at work - we had to do some fiddling to get them to work with 9.10 and 10.04 but the kernal revision used in 10.10 has the drivers right in there from the get-go like the EVTouch driver.

I'm glad. Airline websites have had forever to get this right and yet, for me, one of the most frustrating things to do on the internet is find a flight in any sensible fashion.
