That was pretty much my thought.

If I want to build something that isn't compatible, I can use Xbee Pro
(100mW, 900MHz or 2.4GHz) or 9XTend (1W, 900MHz) and have a complete
radio module with a serial interface.  No radio management required
after initial configuration, power it up and feed bytes into the
serial port.  Oh yeah, and I can have on-air data rates of up to 115k

If these chinese modules work out, maybe they'll be so cheap and
convenient and useful that we (hams) won't mind building a separate
incompatible network; it wouldn't bother me at all to be proven wrong.
 I applaud John for doing the work to try and figure these things out.
