I haven't tried it myself yet, but I would think you could use pfGetTravChan()
in the node draw callback to get a handle on the channel, then use
pfGetChanData() to get a pointer to the channel pass through data. I would
hope that the copy of the pass through data is the correct, frame-synchronized
data of the draw process, but I couldn't find confirmation in the man pages.

Did pfGetChanData() not return frame accurate data?
