I haven't played for a LONG time, but when I did we used CEATs with some minor modifications. It tracks combat second by second, rather than rounds. You roll your initiative (2d10 + Qu iirc), this gives you a modifier to how long an action takes. Each action would take x.x number of seconds. So you just add that to the current time. At each 10 second mark round based things would happen (bleeds, stuns wear off etc..) It took us 2-3 combats to get the system worked out but once we got it, it was worth it.
That sounds interesting. Link?

I am pretty sure it was a modification of an idea from one of the companions, I just don't remember which one.
