Any plans to allow members to pay what they want?

Rather than specifying the cost of monthly or annual subscriptions, would it be possible to implement a donation model? Allowing users to pay what they want as a donation could be a good way of getting non-paying members to make the jump.

Are there any significant barriers to this?


I think this idea relates a lot to planned discounts (e.g. a christmas flash sale).
