Well, there are a lot of tricks you can do to make it less sensitive to
those issues, although none of them perfect, obviously. For example,
caching machine state at each ``critical point'', and using a sliding
window approach to communicating with the peer. It cause some undesirable
``warping'', but it might not be as bad as you think depending on the
frequency of input reads compared to graphics refresh rate and network

I agree, however, that client-server by far makes the most sense in
this case -- I just don't think that peer-to-peer is impossible.
