Just bought a copy of Poker Mavens (Lite) myself tonight, have spent the last 30 minutes setting up a bunch of different cash games and tournaments. Very easy to configure, and you can clone one setup and then modify whatever parameters you want (for example, make a .25/.25 cash game with a $20-$50 buy-in, and then clone it and modify it for .25/.50 with a $40-$200 buy-in). Haven't gotten into setting up rebuys and add ons yet, that's next on the list, but seems pretty straightforward.
There are some security features:
Also seems pretty secure, you can set a password to connect to your site, and then set individual passwords for each different game. You can also issue tokens to players, and restrict games to players holding tokens (for extra security, or for running satellite games, I'm thinking).
One security issue is the lack of https when connecting to the server. Passwords may be vulnerable to hacking, as they are transmitted unencrypted. Not a huge issue, as there is no cash that can be stolen, but it is a bit of a flaw.
You can set up as many games as you want, but with the Lite version you can only run one game/one table of cash and one game/one table of tournament (together) at a time. Once I get a few games behind me, I'll think about upgrading to Pro, which allows unlimited games and unlimited tables, depending on player acceptance.
(Edited to reflect lack of https encryption)
