Hello. I guess this is not possible, and even if it is, it is not a good 
idea to do this. Probably a much better idea would be to start a TCP 
server in the daemon, and connect to it from the other program, and 
communicate using some simple protocol. Another idea could be to write 
some progress info into a file, and open the file from the other 
process, but then you'll have to handle some concurrency problems (not 
very hard, I guess, it will be enough to wait a moment and retry on file 
opening failure). But still I think the server is a better and more 
standard way to do this. Have a look at TCPServer and TCPSocket in 
'socket', it is not hard.

TPR.
