I have the faint idea that somewhere i read that you could gain moves outside of your class. I.E.: a PC has been constantly researching arcane lore and grimoires and has made some quest in favor of a School of Magi or perhaps has been graced with the blessings of a god of magic and through it's efforts gains access to Cast a Spell and some rotes (without leveling up and learning it).
I know i can house rule it, but i'm just interested to know if anybody read something like it in earlier threads or blogs or something on those lines and could direct me to the relevant posts.

Side note: what do you think of the idea?
