It would be very useful. Keep in mind that all oscillators in the system
would need to be coherent so a heterodyne conversion transceiver design
would need to have any other LO's synched as well.

An idea that I have had is the prize for transatlantic 2 meter DX. If
multiple stations stateside had same coherent carrier and were keyed (or
modulated) coherently, there would be space diversity in the transmitted
signal.

Do you think people would like to have a DDS VFO whose frequency and
phase were both direcly related to a common time/frequency standard
like WWV? That is, two people anywhere in the world using the VFO
could make a signal having exactly the same phase as measured at the
transmitter. I would adjust for lightspeed lag using a GPS receiver.

I am thinking this could be useful for coherent CW work.

Opinions?
