Well, when I looked at the ND table on my Mac ("ndp -aln") I daw one of my IPv6
printers but not the other two. Yet I had used them all recently over IPv6,
specifically to investigate whether ND might be a solution to the problem.
Moreover, running "ping6" with a link-local address but no zoneid fails, even
for the printer that was listed...
Perhaps these are implementation issues in OS X, and I intend to continue
testing on Linux and Windows and with some standalone ND tools, but thus far it
doesn't look like ND will solve our particular problems, nor does it address
how we might deal with embedded URIs in IPP responses and web pages without
major changes...
