My hunch is that conflicts aren't as heavy "in real time", because users
can react to them in a more fine-grained fashion. But there's a whole
body of theory dedicated to that. I'd start here [1].
Actually the problems are akin to (but possibly not as hard as)
networked gaming, where you have several clients sharing a common
model: you'll have to cheat a bit if you don't want to wait until
you know the exact model's state, because that'd mean a full network
round trip. Sometimes you can afford that, sometimes not. Balancing
out that and fixing things to hide your cheating after the fact
in a way that the user can cope with the fallout is, I think, the
"interesting" part.

I think network latency would kill you (or rather, your users might ;-)
