Md5sum might be a natural along with rsync protocol 30 but for anything 
else it is going to force reading the whole file to compute before 
attempting to link, make the directory operations slower due to the 
size, and you still have to deal with possible collisions.

I doubt if a database is a better place to store files than a filesystem 
- or if it can do the needed atomic operations any faster.

While it is nice to not specifically require a client, it doesn't add 
much extra work since you have to at least set up ssh keys anyway.

But if you have small numbers of files and a need to poke around 
different versions you should probably be using a version control system 
to manage them anyway (subversion, git, etc.).  In fact there is a 
fuse/webdav layer for subversion somewhere
