[Piers]

I reacently Emailed WPEX about this, got the reply

Hello Piers,

Presently we are distributing the rake taken equally amongst the players dealt in the hand. The rake isn’t just taken after a hand is completed and before a pot is awarded; rather, the house takes the rake from the pot incrementally after each round of betting in a hand. Therefore, the rake is essentially “paid” by everyone involved in a pot, not just the winner of each hand.

We are however in the process if of implimenting a protortional system.
