It's... interesting. However, right now it's just a fancy Space Duel without the sun in the middle. Not bad, much farther than I ever got with my programming, but it doesn't show to me that you're capable of really making a multiplayer EV. A multiplayer EV will probably contain these elements which you don't currently have (outside of networking):
Planets. Systems. A galaxy. Hyperspace. Different weapons, outfitters, etc. etc. etc, all those things which distinguish EV from other games.
Moreover, you have to think through how you can really make EV multiplayer without completely sacrificing what we've experienced in the single player. Nova gives dates to show the passage of time to a player, but in multiplayer you could easily have people running around with different dates if you used the same time system. This messes with "rush deliveries" and a few other aspects of Nova. What happens to a player when they dock at a station? How many players do you plan on having?
A lot of Escape Velocity is about the ability of players to modify the in-game scenario. So if you want a real EV game, you'll have to incorporate that somehow, most likely by having players run their own servers with whatever modifications the admins want. Then you'd have to tie pilot files to each server/mod. It'd sacrifice the smaller plug-ins, but at least we could mod it. Large modifications seem to be part of EV:N in any case.
Anyways, you have a very, very long way to go. Very long way. I'm not saying that you should dump your project entirely by any means, but I don't think what you have is or ever will be anything close to EV4. So I wouldn't try making EV4, I'd try just taking what you have and making it better until you get tired of doing that, for the sake of experience. If you want to learn networking, work on the networking. If you want to work on your programming in other areas, work on that.
'Course, you could just be thinking modestly in the first place... but you have to expect me to start ranting like it's EV4 considering the topic at hand.
