Yes, use the latest code from SVN trunk v10. There is no more difference 
between Delphi and FPC versions for Indy - they are now common code.

No problems, and neither on Linux or FreeBSD. Simply make sure you use a 
port number greater than 1024 (otherwise *nix systems will require root 
access).

I looked at the official IANA list of registered port numbers and chose 
a port number that hasn't been taken yet.

    http://www.iana.org/assignments/port-numbers

Under FreeBSD you can review the /etc/services file. I believe Linux has 
something similar. Or simply use the URL above.

In our case, the user double clicked our application icon on the 
desktop. This started a desktop GUI application, which at the same time 
started the embedded HTTP server (which was built into that desktop 
application). They then searched and scheduled their assigned tasks for 
the day/lesson. They then clicked "view module", which then launched the 
installed web browser with the correct URL as parameter - thus 
connecting to the embedded HTTP server. In the mean time the desktop 
application stayed open - otherwise the embedded HTTP server will 
obvious shut down. We also had a user configurable option that when they 
clicked "view module", it could also minimise the desktop application 
before launching the web browser.

We thought of implementing a Windows Service & *nix Daemon, but that 
would require more effort to install etc. The desktop application was 
the simplest solution and worked perfectly.
