I'm pretty sure
https://pokerclub.now is what you're looking for.
I just tried it tonight, and I'm impressed.
Benefits:
--Runs in a browser (no download)
--No rake
--No one needs an account to join the game (or even to host the game)---you just send them the private table link to join.
--No chance of strangers joining, even if the link leaks, because the host gets to approve each person who tries to join, and set their stack size.
--Reasonably slick and polished interface (keyboard shortcuts for check/raise/fold/call)
--Game host completely controls adding chips to someone's stack (so they can't just rebuy using some play money pool that they have without paying you via PayPal first for the rebuy). And they don't need to have a certain play money balance built up in their account to join your table---this is a HUGE weakness of PokerStars.
--Host control can be passed to someone else mid-game (like if the host needs to leave the game for some reason, someone else can take the reins)
Drawbacks:
--Cash game only, no private tournaments
--NLHE only, no other games
