I would also suggest IPC through TCP/IP.

I have deployed several tools with such IPC implementation which operate

networking library that works in both FPC and Delphi, such as Synapse 
<http://www.ararat.cz/synapse/doku.php/download> (make sure to use the 
latest trunk version). Both Java and C# have extensive TCP/IP components 
so you will have no problem there.

Also FPC wiki has a list of some networking libraries:
