Maybe it would be a good idea to search for other projects doing the
job. How about Owncloud or other server centric application programs?
SourceForge or google code and many others are your friend.

Or ask your colleagues or friends, if they know something helpful where
you can look at the code.

If you find a library written in plain C it's not so complicated to make
an object pascal binding using fpc's h2pas tool.

Additionally you could have a look at relational databases. Locking
schemes and replication would be the keywords.

HTH,
