Yes, but the number of potential bugs when going from OS X -> Linux are far fewer than going from Windows -> Linux.

That's what we do. It works great for us.

It's just a matter of time before a version mismatch or something bites you. My money's on the idiocy of the case-insensitive filesystem.

On our Ubuntu server, I can create both foo.txt and Foo.txt in a folder. On my OSX machine, those are considered the same file.

Three reasons that's no big deal: 1) We never create both foo.txt and Foo.txt. Why would we? (OK, that's a bit snarky.) :) 2) We're developing on the system that's more restrictive (doesn't allow caps and non-caps versions) and pushing to the one that's more permissive. So nothing will get lost in the process. If we were going the other way, or migrating from Linux machines, I could see it being a problem. 3) If this is really a big deal to someone, they can configure OSX to use a case-sensitive file system. May cause other side effects (some Mac backup utilities may ignore either Foo.txt or foo.txt when backing up), but it can be done.
