Can DNAME records be deployed in the wild?

Is anyone trying to deploy DNAME records in the wild yet? There are
various situations in which they might be useful to us if they
worked. (None of these to do with IPv6, incidentally: it's a great
pity that DNAME got tangled up in the A6/binary-labels saga.)
Some specific questions I have in mind are
1. Which nameserver software, other than BIND 9, understands
DNAME in zones for which it is authoritative well enough
to do CNAME synthesis? (In particular, which Windows DNS
Server versions, if any, can cope?)
2. Are there stub resolvers around that cannot cope with the
answers that BIND 9 gives, in which the DNAME record precedes
the synthesised CNAME record?
But I expect there are plenty of other gotchas I haven't thought
of yet.
