Is it possible to make a multiplayer online game with 3DGS that uses a dedicated server, like a Commertial MMORPG? Or should i stop & give up now?

Edit: I'm sorry i have just noticed there are alot of questions about this already, so i guess i should be more pacific,

is it at all possible even with external dlls.

Of cause you can make a GS game and have one (or more with pro version?) dedicated server/s.

Thank you very much mercuryus, i just wanted to make sure before i get my hopes up.
now i must improve my 3dgs skills, because theres no rushing into this ^_^ thank you!

i'm looking for some tips on making a dedicated server, and how the client connect to a specific IP
