We would appreciate if you open up a new topic rather than reviving an older one. For this time I have split your post from the older topic into a new one.
Now, back to your question. It all boils down to the shell provider, meaning how many (amount) background processes each user is allowed to have. An eggdrop can be on a single network at a time, so if you want one on two networks then you need another one to be connected on the second server, meaning second background process.
Check with your shell provider about the amount of background processes you can have.
Once the game is over, the king and the pawn go back in the same box.
