Make sure your school permits releasing your project as open source.
The school I attended probably would not allow this. Also make sure that
GPL is the license you want, though that's a flamewar we don't need.

This is a fundamental problem. If you can't trust the people you're playing
with, then a peer-to-peer design is worthless.

These aren't the only two options, of course.

For small-scale stuff, yes. If the simulations get really big this requires
too much compute hardware and bandwidth in the main server. If you don't
aspire to something on the scale of UOL it should be fine.

It's pretty easy to authenticate who you're talking to. It's impossible to
prove that they're trustworthy.

Open source doesn't change much in trust situations. You can demonstrate
that there aren't traps in the source code, though.

Usenet, mabye? :-) I can't think of any games like that. Well, maybe
card games like MTG, but they have cheating problems.

I'd recommend a hybrid architecture. Insteed of a single server, use a
network of computation peers that interact using the DIS protocols. Each
of these can have several "display clients" which take care of UI stuff
without handling any computations that need to be trustworthy.
This can be set up so that all of the critical computations are controlled
by whoever set up the game (presumed trustworthy), while maintaining the
scalability of peer-to-peer design.
If you have a trustworthy network and players, just use one peer per player.
For smaller games, just use one peer as the server. They handle multiple
clients, right?

This depends on what you consider acceptable behavior. A lot of games like
this can have "cyborg" or AI players. If this isn't a problem, then you
can trust a fair amount of data to the client. If it is, you have to trust
the client to some degree. Design your system so that data you care about
can't be compromised by people/code you don't trust.
