I'm curious as to how this model will work if users can't easily deposit money online. I can only imagine they will inevitably face the same problems as online poker where credit card companies and banks will block any transaction related to gambling sites or 3rd party eWallet proxies.

In the early online poker years, you could easily deposit directly from your bank or credit card. Then banks started blocking these transactions. The online casinos came up with the eWallet proxies such as Neteller that served as an intermediary between the banks and the poker sites. Those too were blocked. Then gift cards became the main funding source, and eventually those were blocked. Eventually the process ended up with direct wire transfers or payment-by-phone. As each deposit method was blocked, it became harder for the casual players to get money online and they stopped playing.
