Steve,
I finally received more information from brushelectronics and just
learned that the source files dsPIC_Bootloader_Target.tar.gz
should not be distributed as they are part of a restricted license
purchased product.

It turns out that Jim did not customize the standard paid version of
the boot-loader but paid brushelectronics to create a customized
version for the voter board, then another customized version for the
RTCM.

The binary can be redistributed but the source can not.  I have a
license to use the source but under the condition that it not be
redistributed. It is the same as the license that Jim had.  The
license is per person and not per project so if multiple people are
working on the same project they each need to purchase a license.   I
am currently working on a little bug in the boot-loader related to the
ethernet chip initialization and will provide a new binary of the
boot-loader if I get it fixed.  The bug only effects the RTCM version
not the voter board version.  More info to follow as I make progress
on this.  Updating the boot-loader requires a pickit3 so probably not
something most people will want to do.
