since there's only one input channel for a program (stdin), and raw_input
reads from that channel, I don't think there's a portable way to do this.

on unixoid systems, something like this could work:

    import sys

    text = sys.stdin.read()

    # rebind sys.stdin to my tty
    sys.stdin = open("/dev/tty")
    sel = raw_input("Selection? : ")
