I've been thinking about bluetooth and the M100. It seems to me that
the best "achitecture" for mobile net enabled apps would be as
follows-

1)  M100 with an RS-232 bluetooth dongle (hardware flow control!), and
REX of course.
2)  a smartphone, with WiFi support
3)  optional - a NADSbox with an RS-232 bluetooth dongle
4)  a better terminal program for M100, as an option ROM, including XMODEM

It is easy to instruct bluetooth to connect to either NADSbox or
smartphone.. This can be scripted basically.  We know that TPDD
protocol runs well on bluetooth now.  Also, a version of Desklink
could be made for Blackberry.

Then, all we are doing is writing apps for Blackberry, to adapt text
email, bulletin board, downloads etc.

I think this would do it all, and avoid any further custom hardware.
The Blackberry and NADSbox can sit out of sight, and all you'd need is
an RS-232 Bluetooth dongle on the M100.
