remote file access

I have a very limited set of file system reads/writes I need to
implement through sockets to a remote machine.  I have been using
the socket components (the non-indy ones) for other client server
communication and am now wondering what the best choice would be
to  implement this new functionality.  I am hoping to implement
this similar to a diskread: read <supply directive on what to
read>, block, wakeup when data is ready.  Is there an example of
this I can review?

Thanks!
