This would be my preferred solution.

It might be helpful to list the voltages and currents the supply is 
capable of.  I suspect most of the power is +5V or +3.3V.

Yes.  If we have a Tx that runs power, it will probably run from 13.8 
VDC or some other voltage, not supplied by or through the Atlas backplane.

> Also how many folks would be interested in this type of supply.

If I knew it was sufficiently quiet to include a decent receiver in the 
same box, I'd be very interested.  But if it is noisy, then for many 
radio applications it wouldn't be suitable.  Like the old 
liner-to-switching-to-linear 5V regulator exercise we went through with 
the SDR-1000 back in '03.
