Presuming that the dynamic system is a Linux box, sure. However there
are a LOT of devices that can utilize dynamic DNS that do not have the
capability (through the provided interface(s)) to make those types of
changes.

Not everything can do an IPSec tunnel, nor will all devices in between
play well with IPSec tunnels. We don't know enough about the endpoints
and / or what is in between to know if any thing like this will work.
If this will work, this may indeed be better.
