Membrane Matrix Keypad and XBee?

Is there a way to connect a Membrane Matrix Keypad directly to an XBee rather than using a micro controller between them?

No. You need a micro to decode the keypresses.

I guess I don't like taking no for an answer

So I got it to work with no micron between the matrix keypad and xbee. I basically use a resistor ladder as defined on this instructable I foun....and viola!
