And with
Laren giving us the latest correct submission, I think it's time to close this contest and put you all out of your misery.

No, only joking. I meant to say, of course, it's time to reveal the answer.
The key is to take the strings of numbers:
94280360968043804309680685847590749029064631
73630630968702679370270206862370290774828306377243 066591
and map them with the numbers on a standard modern telephone keypad, such as the ones you may see on a typical mobile telephone - where each key corresponds to certain letters of the alphabet - 2=abc, 3=def, 4=ghi, 5=jkl, 6=mno, 7=pqrs, 8=tuv, 9=wxyz; and on many phones, 0=space/carriage return and 1=general punctuation. A good way to see this in effect is to type them out on your text message facility on your cellphone if you have one - or just work things out yourself, really.
If you do that, you would get this message:
What do you get if you multiply six by nine?
Send me your answer as a number by private message only.
To which the answer, and the answer to this puzzle, is
54.
Simples.
Oh, and the "Beloved Aunt" reference? Well, "aunt" corresponds to the keystroke sequence 2868, as does another certain word which famously got Larry David in trouble...

(Interestingly, the word "bunt" isn't offered on my phone...
