XBEE and MAX232/CP2102 parallely

Hey guys.. I have a situation...

I would like to connect an XBEE and a MAX232/CP2102 (USB-UART) parallelly to atmega's RX and Tx pins. Is it possible to get them connected and get them working without hassle?... What all things do I need to consider before attempting to connect them....

Thank You

I would like to connect an XBEE and a MAX232/CP2102 (USB-UART) parallelly to atmega's RX and Tx pins.

Will the XBee be mounted on a shield, forcing it to use the RX/TX pins? Why not use two other pins, and NewSoftSerial, for one of the devices - probably the MAX232 one, since that does not come on a shield, forcing the use of specific pins?

If you have two devices on the same set of pins, how will you know where the serial data is coming from?

Only one of the devices would be used at a time. I would like to hardwire both of them to decrease the burden of removing/inserting the XBEE.
