Thanks for the starting point there. The calls to Swupdate don't seem to be working since the LM Flash Utility still hangs on the "trying to connect". Starting the MAC/PHY with the "SoftwareUpdateInit()" function, my callback function is called as expected. I get the same behavior with the Energia UDP/Ethernet libraries where I can see the "magic update packet". 
 
I suspect that the issue is that I don't have the proper Ethernet Bootloader installed, but can't seem to find any information on how to install/build it. Any idea how I can install the Ethernet Bootloader/include it in my projects?

I got the Ethernet update to work by making a few modifications to the SwUpdate.c file. For whatever reason (I didn't really bother looking into this part...), the defines aren't set to use the ROM based Ethernet bootloader in the SoftwareUpdateBegin function, and the ROM Ethernet functions aren't defined in Energia 017's "rom.h" file. The latest version of TivaWare (TivaWare_C_Series-2.1.2.111) does provide the proper definitions for it. I simply added the necessary defines to call the ROM_UpdateEMAC and forced the code to use that, instead of the flash bootloader based update system. It also seems to be important that the MAC address set by the Ethernet library matches the MAC address programmed into user registers (by default this is what is on the sticker on the board).
 
Anyways, I've attached a working Energia example with support for updates over Ethernet.

Are you doing any filtering on the sensor output? I'd suggest setting up an RC low pass filter to smooth out the jitter, and then maybe oversampling the data (read it 2-10x more often than needed) and applying a moving average on the data. 

For those interested, I also have a pretty cool (if I must say so myself...) Processing <-> "Arduino/Energia" library on GitHub: https://github.com/sopgenorth/MSOE_ROV_2015 . It communicates a set of variables to/from the two devices over UDP, and is pretty easy to use and get going.

holy cow - it's working
 
it is possible to add this programming method to energia?

Awesome that you got it to work!! I'll give it a try and include it in Energia as an example.

Try the attached Sketch as a starting point. I only made it compile you will need to fill in the setup/loop portion.
