Is it possible to use the telementry channel for non-packet radio
transmission of messages? Conceptionally I'm sure there is not much
differences between a telementry message and a normal communication
text message.

If so, is it legal? and how hard would it be to construct this, and
what protocol should it use? morse code?

I can see this being used as a pager system for groups of people for
non urgent messages.

As far as I can determine, any data mode is permitted. The only restriction 
is that transmissions must be less than 3 seconds in every minute.

This is deliberately to stop packet radio, which can run at a duty cycle of 
more than 50%. The rule limits use  to telemetry and telecommand style use.

I'm sure other use could be made of the data channels, within and without of 
the regs.
