I know usb and bluetooth device support was added as of gingerbread,
wich is 2.3 so if your device is at least that current you will get
that functionality.
as for "kiosk'ing" the device i am not sure, i do know you can launch
an app on boot. but i have not delved into how that is done.
however there is no full jvm for android at this time, but in theory
you can tailor an install of linux to run on arm and essentially use
it instead and then you could add a jvm... i would suggest a distro
that has an arm branch in their repo's or something that will use
global environment variables to compile compatible code.

Does that mean it would be possible to run a standard Java application without the load of a full JVM? Is all compiled Java code end up being 8-bit bytecode that could be directly run on this CPU?

It is possible to somehow either add this functionality via replacement kernel modules or perhaps even rebuild a new/different kernel for one of these devices to enable this? I have looked at some of the dmesg output from one of my el cheap'o tablets and I see some things happening there when I plug in a keyboard but not enough apparently.

A mouse trap, placed on top of your alarm clock, will prevent you from
rolling over and going back to sleep after you hit the snooze button.
