Hmm, like Advanced Learning? I think the anyspell ability makes that a bit redunant. Now, some spontaneous metamagic might be interesting, maybe let them pull it off with Spellcraft checks...Finally, it might make sense to let them customize the spells they have access to. Perhaps something similar to the ability given to the Warmage or the Dread Necromancer.
EDIT: Okay, fixed the typo, changed the casting, and added in the metamagic lore ability to let these guys get spontaneous.
