If that is your plan (and I have no beef with it - you are perfectly
entitled to try to protect your investment just as we are perfectly
entitled to try to evade it :-)) then it would be good to continue to
have the modem part of the new hacker board populated. My intention
was to use one as a means to interface a VoIP system to a POTS line
for non-VoIP calls IYSWIM - so that I could merge incoming POTS calls
with the VoIP system and/or manage my own VoIP-or-POTS decision

Why not offer it at a higher price that makes a profit *on the unit*
and had no hardware-hacker-defeating mechanism? You could even do that
now with the E3 and make it flashable with an image from the SD card
or a USB memory stick or somesuch. And thinking along those lines, it
has no need of the larger of the two sets of flash on board if it has
the SD card socket - it can boot from the small flash bootloader and
then take its image from the SD card. I don't believe it would be
cannibalising your own market as I think it would be a completely
separate market. It may of course be that if you remove the subsidy it
becomes more expensive than something that could be assembled at home,
but the fanless, single boardedn-ess of it is attractive.
