real time online networking for a game is unrealistic at this point with C2. there are other, more specialized tools out there for MMO creation that are better suited to this end than C2 is. having said that, MMO creation is still difficult. there is nothing wrong with setting such high goals for yourself. just realize that you probably will not succeed. <img src="smileys/smiley1.gif" border="0" align="middle" />
unlike you, I'm too scared to even try making an MMO <img src="smileys/smiley9.gif" border="0" align="middle" />
Edit: take a look at this: touchofdeathforums.com/eclipse
The latest version is called "eclipse origins." it is nowhere near the flexibility of C2, but may be a good start
Edit2: I do recall reading about a websocket plugin for c2 somewhere on forums, so if you have an immense amount of programming skill...you could actually get it done! <img src="smileys/smiley2.gif" border="0" align="middle" />
