...has there been any work done to share blocked IP lists and spam blacklists across wikis
http://meta.wikimedia.org/wiki/SpamBlacklist_extension can be made to use Wikimedia's spam blacklist or one from any other MediaWiki site. It's best to use it in conjunction with the spam whitelist in case Wikimedia are blocking sites you don't think need to be blocked.
For blocking IPs and usernames across wikis, Wikia have developed RegexBlock. See http://www.mediawiki.org/wiki/Extension:RegexBlock
There is also Wikia's SpamRegex which is useful for blocking non-URL spam. See http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/SpamRegex/
