caster madness

[urbanpirate]

gestalt build, dual progression classes (theurge and such) and prestige on one side of progression (at a time) how would one get the highest casting ability in the most classes?

[Aspenor]

Spell to Power Erudite//Archivist. You now can learn every arcane spell, divine spell, and psionic power ever printed, and they all key off your INT.

Done.

[Tvtyrant]

Wizard/Shadowcaster/MT//Bard/Sublime Chord/Ur-Priest/MT for quadruple 9s. Then watch as its mostly pointless since you can only cast twice a round anyways.
