[OZAPRS] Choosing software (linux)

[Liz]

The home digipeater and / or iGate is getting closer....

I've got a robust Debian setup on the Pogoplug, the new antenna and
radio are now arrived and getting closer to install.

I can reach the digipeater network reliably with a beam and 70W output.
Mobile is not reliable transmit or receive with 50W on a vertical
antenna.

I'm thinking about 2 different scenarios 
(A) Put the new vertical on the house, connect to the D710 and run an
IGate with the Pogoplug. At times this would connect to the digipeating
network through VK2RGF (dependent on atmospheric conditions).

(B) Put the new vertical on the house, connect to the Yaesu single band
with the Signalink, connect the dual bander to the beam and connect
both radios to the computer. Use some software method to
transmit/receive APRS data on both radios. Possibility of internet
connection if digipeat system fails (maintenance, bad weather etc)

I'm looking at aprx dixprs aprsdigi 
What other software should I consider (low power headless linux box) ?
