Aaron Swartz suggests expressing software/IP licenses as haiku:
MIT: take my code with you / and do whatever you want / but please don't blame me
LGPL: you can copy this / but make modified versions / free in source code form
GPL: if you use this code / you and your children's children / must make your source free
RIAA: if you touch this file / my lawyers will come kill you / so kindly refrain
