Right.  This is exactly what 'dftp' allows.  It brings up all packages
that it finds and allows the user to choose what to do.  If 'dftp'
brings up two instances of ghostscript, the user just selects one
and/or deselects the other.

I agree.  As long as dpkg will never install more than over version of
a given package (it would at one point), the current solution is fine.

It does make the distinction, though it may not be immediately obvious.
Because the full path to the package is listed, the first component of
that path is the distribution under which it was found (i.e. stable,
unstable, contrib, non-free).

 the difference between theory and practice is less in theory than in practice
