The way the Linux Foundation handles this process in their conferences is simple: you find the best trip, get approval from Angela Brown (Linux Foundation), book your trip and the LF will reimburse you. If you have been approved and you don't have anybody around you with a credit card to do the booking then contact Angela and explain your case. This is no guarantee for anything but she is the one that will be coordinating these reimbursements.
of course that would be possible, but how many developers would be attracted by community-only prizes? In case of the last competition that was around 30€.
I just want to remeber that we still need some volunteers for the next competiton.
I think it would be good the have a official maemo.org PayPal account this time.
It was no problem last time, but I had the impression that many refused to donate some money because of the private nature of my PayPal account.
