I have been experimenting with Debian Live on a USB stick and I don't
find the read/write speed to be a hinderance.  Of course "slow" is in
the eye of the beholder.  I'm using an 8 GB cheapo USB stick.  I don't
know what the specs are, but I certainly didn't pay extra for a fast
one.  I also haven't experimented with very large files.  I typically
use LXDE or Fluxbox as my GUI, which may help the speed.

My understanding is that there's an optional feature with Debian Live
that lets you run everything in a ramdisk, and it syncs to the USB at
logout/shutdown.  This is similar in concept to #4 above.  Don't ask me
how to set it up though -- I'm still a novice with Debian Live.
