a) OpenTRAC and APRS would not be transmitted on the same
frequencies, so the translator would be functioning as a
cross-frequency repeater;<br>

Someone, somewhere, sometime wouldn't realize this design intent and
would do it anyway. Long after anyone that knows the ramifications
has moved on to different pastures.<br>

b) the APRS-IS backbone would never carry native OpenTRAC
packets (a separate backbone would be needed to carry the
different binary packet format).<br>

Theoretically, if you make them 3rd party packets on RF, it might
help?<br>

But you're right; a loop could still occur if two translators
were "back-to-back" in the network (either over RF or via
I-Gates on the APRS side), because translator#1 wouldn't
recognize that the output of translator#2 was a previous input
to translator#1 (even without the other issues you mentioned of
digipeater/I-Gate mangling of packets).<br>
</div>

<br>
Yep, and loops are bad, very bad as you already know.<br>
