So far I've just run Android x86 on VirtualBox, intending to capture
video via the host should I get to that point. It's using desktop
resolutions by default, however, so a portrait only activity will
still get given a screen that is wider than it is tall and look
screwed up, for example. None of the options in the vga=ask boot
option seem like they can fix this alone, although maybe if I could
figure out how to change the orientation as well, or tried a different
VM with a different virtual video adapter. I haven't gotten the
UVESA_MODE boot option to work. Guess I could change the apps I want
to record to better handle the bizarre resolutions.

Yeah, I read in a review that the Evo 4G is useless for this. I was
thinking of the Droid Incredible with TV out accessory when I wrote
that. I saw a video of it outputting the home screen at least, so
there's a chance it can do apps as well. Not sure if it outputs HDMI
or something else.

Are you interested for the purposes of showing Android full screen on
a projector during talks and classes? My favorite thing for that so
far is to just run the emulator skinless, with the "-skin 320x480"
command line option, for example, and then set it to full screen mode
using the key combination for that. Looks better than a document
camera, for non-OpenGL stuff anyway, in my opinion. I tried installing
a custom mouse pointer that looks like a huge finger, so people can
better tell where I'm clicking, but the emulator seems to override it
as soon as my mouse moves over it. So that's a drawback, I guess.

I have to use Android 1.5 with that method, unfortunately, because it
gets better frame rate on the emulator than 2.2 even, but it crashes
all over the place outside my apps, like when playing with the
wireless/airplane mode in the settings app. I assume you could use a
modern, bloated Android version, though.
