Don't know.

It is. PKS does not support multiple subkeys and some
other features of modern keys. Actually nearly all
keyserver administrators switched to SKS (it syncs
fine and supports all recent keys).

Should run on SuSE without too many problems (I have
installed SKS on a SuSE system). Hopefully you have
the correct version of the OCAML-Compiler etc. Just
ask at the SKS mailing list, it is usually low traffic
but very responsive.

I guess not. There are some problems with recent public
keyservers (which are not technical problems but legal
problems, eg. privacy of the data (because keys actually
cannot removed or blacklisted)), but this does not
matter for a private key server. But a keyserver is
something completely different than GnuPG, so the
crypto gurus take care for GPG and some other gurus
develop key servers. Maybe a key server that supports
cryptography would need a team of both. Any takers? ;-)
