That 'This is a test!' isn't a binary edit, I actually modified the XAP file and added a line to the script. Since I'm using existing code all the animation is already done in the script when that pop-up window appear.
As for the FTP server, it's very possible, but that'll required de-assembling the XBE, adding code to create a thread. A nice feature would be to create a thread that loads DLL files from a plug-in folder. If the Xbox doesn't support DllMain, we could easily add support for it from within the thread. In essence, with this plug-in feature, anything could be possible.
As for help, we need an editor for these XAP files!!
Just tried changing the skyColor to 0 0 0.2 (it's a bit hard to see, but there's some blue in the background)
Tried adding a color property to the shell transformation, but it crashed (RIP) saying Unknown property. So, it's one thing to change the script, but it's another to change it with valid stuff, following the proper syntaxes/rules. As for the text color, I think they use textures for such thing. Sure, the "text" itself are primitive drawing, but using textures and not solid colors.

-Volt.
