I've got to create a Final Year Project for my CompSci degree and an online poker room is seeming like a good idea.

So I'm wondering what everyone looks for in a poker room?
Anything you would like to see but no one currently offers?

It is VERY unlikely that if this project gets built it will get past the play-money stages, I cant imagine any way for me to gain the money to be able to attract people to play (big sign-on bonuses and such). But i still think its a good idea for a project and will be a laugh too.

So I'm really looking for Game ideas, rather than money ideas (rakebacks and such).

At the min i'm just trying to work out an effective and efficient way of shuffling the deck.

So any ideas are welcome.
Do you like nice/fancy graphics? Or is something simple best?
Does everyone play on windows or would a cross-platform version be better?
Is multi-tabling important to you?
