A sponsorship is very doable and tax deductible. So is a support contract. Or buying a the docs in a the form of a PDF -- or anything I buy, really. Donations are legal (I think), but might not be tax-deductible. All business expenses are, though (since you pay taxes on profit). Rule of thumb -- business benefits from it. Donations are tax-deductible by individuals only to the extent you don't benefit from it. Also, Patrick is in Japan, where things might differ.
