Maybe, Depending on which Arduino you have.
Uno Supports 1 TX,RX pair in hardware more with Software emulation (SoftwareSerial)
Mega Supports 4 TX,RX pairs in hardware with more via Software Emulation (SoftwareSerial)
I'm not familiar with the rest of the Arduino Family.

Check out my Kickstarter Project Memory Panes an expansion RAM Shield for Mega2560's. It adds 1MB of RAM for those projects where 8KB is not enough.
good to know
When I've used an Arduino Leonardo before I use pins 0 and 1 for USB and pins 8 and 9 to connect to an Xbee device. You have to use the Software serial library.
