fundable.org is a site that will facilitate donation collecting for a certain project (feature, bug fix, app port, develpment machine, etc), but refunds peoples money if the target dollar amount is not reached. could be a way to get those donations rolling. i bet more people would donate if they felt there was a specific "goal" that was tied to their donation. just a thought.
