How does the Meta Word Mastery feat function for a multiclassed wordcaster?

How does the Meta Word Mastery feat from the Words of Power section of Ultimate Magic (pg 166) function for a multiclassed wordcaster?

Does every wordcasting class add 3 additional meta word castings per day? Or are the feat's 3 uses usable by any of the character's wordcasting classes, whenever they've used up their own limits?

Does each class get a new meta word?

Should this feat have had a Special section, allowing it to be taken multiple times, with each choice applying only to a specific class?

I don't know the answer, but I agree it's a good question. It's not clear whether a multiclassed wordcaster has one pool of meta word uses, or whether each wordcasting class has its own pool of meta word uses.

If you think that each class has its own pool of meta word uses, then I agree that it would make sense to take the feat multiple times as you note above.

Along the same vein, the Experimental Caster feat doesn't seem to have an option to take it for a second class - it seems that if you select it multiple times, you improve the set of options you have available for the class you chose the first time, but you don't have the option to apply the feat to a new class. Was this the intended behavior?
