I don't have a particular problem with running amd on a laptop unless
I have NFS mounts active when I disconnect (a small piece of elisp and
a shell script help prevent this).  If I understand CODA then it will
probably be better, but not perfect.

Done using a name in /etc/hosts which changes target depending on

The problem is that much of this is done `manually' by scripts which
know how to behave in different places.  It always seemed as though it
should be possible to make it automatic, bit I've never done it.

USB may be your friend for the keyboard switching problem.
