Sugestion for 1 project multiple machines?

I’m on three machines during the day and would like any suggestion on a way to work on the same project from each machine without using something like a flash drive.
Thank you kindly!

Well I can tell you trying to have you project contained in a SkyDrive or DropBox doesn’t work because of lock contention, the update process is too slow.

It is easy though if you copy your projects from the ‘cloud’ drive wherever your starting work unless you have one of those gigabyte projects.

I don’t believe the size will get that large. I’ll try DropBox. Thanks!
