Searchable archives? Best practices?

Is there a searchable archive of the mailing list?  Are search engines
able to crawl the archives?  It looks like they are but are they
complete?

What are considered best practices for connecting Cyclades ACS to
conserver?  I'm transititioning an existing installation so the
Cyclades are not on a dedicated management network.  I want to run SSH
between conserver and the Cyclades and right now I'm contemplating
installing an ssh key on the conserver server so it can connect to the
Cyclades.
