In the end you will need some sort of sync-method.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

I succeeded by using UDP, but the lag is considerable and my stations end up de-synced by half a second of what the AP is showing.

I'm surprised by that. UDP should be quick. I wonder if it is an implementation issue rather than UDP.

To be honest so am I. If I want fast (but not guaranteed) comms between UNIX boxes I use UDP.
