The only way for a program to open ports below 1024 is to start as root.

However, the program must drop privileges for all other issues that the port privilege, otherwise a disaster is waiting to happen.

 

Olaf Kirch gives the key to this in his small article from 2006:

I imagine that one could use Olaf's program to spawn a child process that would inherit the raised privileges for setting up ports below 1024. I will work on that next week.
