I added it to fpc/packages/fcl-base. It compiles OK, there are no dangerous 
dependencies except sysutils and classes.

Juha, if you want to implement the single IDE instance, then I would like 
to ask you to implement this in custapp.pp. This is useful functionality 
for all kinds of applications, and is since very long on my todo list.

I think the functionality can be split out in 2 parts:
- Make sure a single instance is running.
- Sending messages to running instance.
The first can be implemented in custapp, I am not sure about the second.
At first sight, I think that this should be possible.

Michael.
