I use OLE under Windows and translate mime-types to Windows CF_xxx
clipboard format. If it's a fpGUI app to fpGUI app, you can simply use
the mime-types. Under Linux I use the XDND protocol, which already
uses mime-types as standard, so no translation necessary.

I did a quick google search, and it seems under Mac OS X you can use
the Carbon Drag Manager. fpGUI doesn't officially support OS X yet, so
I don't know further details.
