You may have full access to all hardware on =your= computer.  You may
even have that access in source code that I, or people I trust, get to
look at before we compile it and run it on =my= computer.  But bear in
mind that no userspace program needs access to the hardware.  Only the
kernel (including device drivers) needs that access.

And there is no way that Joe Blow's Website gets to download a program
to run on my computer and do God Knows What.  I might let Joe send me
a java applet that runs in a sandbox where it can't try to sniff
credit card numbers, bank accounts, passwords, etc.

If that stunts Joe's development as a programmer, so be it.
