Is there a minimum wagered requirement? If not, that won't really stop anyone from creating multiple accounts.
Would you also disallow multiple players logging in from same ip to play at the same table or same tournament?
Are there going to be a separate balances for poker and dice, or can players use the same funds to play both?

Requiring wagering for this is shame, you offer VIP? That's good, I think first two is already enough but if you require wagering a lot this isn't correct action and mustn't be acquited by the words that you only do this to make it difficult for people to create alt accounts.
Even it won't work.If I have some money to spend here, I will wager, also there is possibility to ask friend for verification here and not a one friend, a lot of friend, will wager on all account because have money (for example). So not a big deal, better to use different strategy.
