How many spaces are actually being transmitted by the VX-8R.  Are you 
sure it is 2 at the end originally?  Some things out there in the wild 
add spaces at the end of a line also.

VK2HIM-1 via VK2RUW-1 with no spaces is a UI-View IGate

VK2ASY-1 via VK2RUW-1 and VK2RAO-1 with one space is APRSIS32 running an 
AGW RF port

VK2ZEN-5 via VK2RUW-1 and VK2RTZ-1 with two spaces is APRSd or similar

All three involved digipeaters are apparently running UIdigi.

Unfortunately, there's no remote indication of what hardware/software 
TNCs and what interface modes (KISS or CONVerse/Host) are actually in 
use in these various stations.  You'll have to contact each individually 
to make that determination.
