Yes, this will be possible - I will go in to more detail in a blog post, but essentially you will be able to create a group of people who can pool resources, and then pay for servers with funds from that pool.

It might not be in the beta - if not, I will add it soon after. I have a few features aimed at groups/clans, as anecdotal evidence suggests they are the people most likely to pay for a server.

Would personally love this feature. It's too expensive to pay hosting alone, just to play games once a week or so.
