Ok, so indeed intresting times we live in. The donations can be send in paypall to admin@shipbucket.com account and all cents counts, so lets do this and get it working!

Does the currency does any difference? Does it have to be Euros or US Dollars or it could be anything?

If such can be made technically feasible, we migth add that sort of feature for examble as paid extra service for expanding our budget.

naturally the feature would be only available for the SB members. But as you said yourself, since the stuff is allready downloadable by itself, there isen't actually that big need for such feature at all, but making one would mean work and that work, as outscored now, costs, and those cost would need to be covered.
