Booting from flash drive IMG file

[SpyderPLUG]

Hope I put this in the right place, new here. I did some searching here and found a couple threads relevant to what I am trying to do, but with my limited knowledge with Linux, I figure knowing some info will just get me into trouble.

I am trying to set up a Mythtv backend on a v3 Pogoplug, I have a LAMP setup working, but I am lost when it comes to setting up VNC and X11. It seems that every package I install needs something that needs to be set up, that needs something....
I found Plugmyth and tried to set that up(on a separate v3), but the instructions don't work with the newer models. The command line changes at a certain step and then there is no response. I am still able to see this plug in cloud storage, so no harm done(can also SSH). So my question is, is there a way to use the instructions to set up ARM and have it boot to a extracted IMG file? The plugmyth file was on megaupload(so I can't wget the file). If it needs to be extracted from boot, can I wget from LAN?

If you can give me some pointers to these sources.. I might better be able to help.

The instructions don't work on newer models for a reason.

Here's the info, http://sourceforge.net/apps/mediawiki/plugmyth/index.php?title=Main_Page
Their support forum is dead, and I figured I could use the instructions here to modify theirs.
System requirements list 'Pogoplug', maybe there was only one version when this was made. It lists "designed to run on Sheeva platform", is that a dealbreaker right there? I didn't know all the technical details until it failed and I tried to figure out why.
