I wonder if this would be useful on 6 meters as well?

New EmComm Software for Windows Now Available for Beta Testing (Jan 3,
2008) -- The NarrowBand Emergency Messaging System (NBEMS) development
team announced earlier this week that a Windows NBEMS software suite for
beta testing is now available. NBEMS for Windows is a suite of software
programs designed for point-to-point, error-free emergency messaging up
to or over 100 miles distant. According to developers Skip Teller, KH6TY
and Dave Freese, W1HKJ, the NBEMS system is designed primarily for use
on VHF and up, or on HF with Near Vertical Incidence Skywave (NVIS)
antennas. The system uses the computer soundcard as the modem. Other
than a simple interface connection between the computer and transceiver,
no additional hardware is needed. Composing and sending emergency
messages on NBEMS is no more difficult than sending e-mail via the
Internet. All forwarding is done by stations manned by live operators on
both ends who can confirm that a frequency is clear locally, or
negotiate a frequency change to avoid causing interference. The NBEMS
software can also be used for daily casual communications on PSK31,
PSK63, RTTY or MFSK16 and is capable of sending flawless, high
resolution, passport photo-sized color images in less than 10 minutes
over any path that can sustain PSK250 without excessive repeats. Radio
amateurs are invited to participate in the beta test of the NBEMS. The
NBEMS suite can be downloaded for beta testing from the NBEMS Web site.

With Skip Teller it is a proposal for something besides Winlink2k Pactor
II/III comms. Low cost using your sound card.
