As Owen said the first part is syncing the start (like you would anything else non automatic, with some kind of remote call).
If you want them to look the same set the seed on the partical system to the same value on all players: [ParticleSystem.randomSeed][1]
The PRNG (pseudo random number generator) will generate the same numbers if you seed them the same. When you let a particle system start up without a seed it picks a random one.
I'm not 100% on how the particle systems work (so may be some other entropy at work), but it's worth a try. I've done this before for generating repeatable "random" stacks of cards where I have to reproduce the stack (so I just store the seed value).
