Interesting question. The files in /var/lib/dpkg/info are mostly constant;
the scripts in particular, so those could/should possibly go in /usr.
However, /var/lib/dpkg/available and status are databases, which puts
them in /var.

Only dpkg and dselect and apt usr /var/lib/dpkg. Your clients might not
need it at all; if you do all package installation/maintainence on the server,
it won't matter if it doesn't exist on the clients or is out of date.
I experimented with remote booting and NFSROOT here a while back.
My template /var/lib for each client machine was empty.
