The PDF that lists all the supported devices for that unit (and it's big) includes these lines for the PIC model that is used on the EtherDongle:
Microchip PIC32MX795F512L [TQFP100 12x12] DIL40/TQFP100-1 ZIF PIC-1
Microchip PIC32MX795F512L [TQFP100 14x14] DIL40/TQFP100-2 ZIF PIC-1A
Microchip PIC32MX795F512L [XBGA121] BGA-1354/0970 = BGA-Bottom-209 + BGA-Top-103 ZIF-CS
Microchip PIC32MX795F512L (ISP-2wire JTAG) Note: via ISP connector
Microchip PIC32MX795F512L (ISP-4wire JTAG) Note: via ISP connector
Microchip PIC32MX795F512L (ISP-2wire JTAG-ext.VDD) Note: via ISP connector
Microchip PIC32MX795F512L (ISP-4wire JTAG-ext.VDD) Note: via ISP connector
Not sure if the "ISP connector" they reference would be compatible with the ISCP connector on the ETD. Then you'd have to figure out if that programmer can read in the hex firmware files we use with the PICKIT. I suspect you'll have to do some research on your side. Might be easier to spend the short money to pick up a PICKIT3.
