That's exactly what I do - "remote" repository in dropbox and push/pull in a "local" copy in my home folder. Works just fine for sharing code between my own PCs. I use it only for my personal projects, sharing repos this way is just asking for repo corruption -- if you both push at the same time, say goodbye to your repo.
