It'll be interesting if this ends up taking off.
More info here:
Hacker Dojo is a California Nonprofit Mutual Benefit Corporation. Fully tax-deductible federal 501(c)(3) status will hopefully happen when things settle down.
501(c)(3) would work for the Dojo under Education, [Technical] Literacy, and Prevention of Cruelty to Children or Animals.
Also, being as helpful as ever, google tells me 501(c)(3) = 450,588,064,374 m/s
