hi smotsholle,
well you did not entirely understand the problem....we're making an emulator, we don't have the client's sources so the only thing we can change is the server-side(aka our code )...we've tried to implement bezier curves and though the curves are calculated ok in the test app we've made, in the game it looks weird...also using bezier curves is quite a punch for the network traffic since sending 5-6 movement packets per second per moving object is quite a lot....the method you've described would work (will try testing it out), but as you said big lags will cause players teleporting around....
