hi, Ive been curious about something lately when Ive been working on an idea, and I dont have a multimeter or anything to read the current and such, but what Im curious about is:

What is the current consumption after you shut the thing down, before you unplug it, when everything has shut down, but the power LED is still on, and does having stuff plugged into usb (mouse/keyboard increase the current drain, or does it turn off the usb ports when it shuts down?
If it isnt smoking and blown into pieces, it's not pushed far enough yet. :P

No, the USB sockets are still live, as the power to them comes straight from the power in.

My Pi drew 110mA after a sudo poweroff command, before I unplugged it from 120VAC 60Hz. Only think plugged into USB was a Powered USB Hub.

Hope this helps!

thanks for the reply dacmill4 and burngate, I have a general idea on my project now.
