I have multiple mediawiki installations, and I'm wondering if it's safe to allow them to all use the same memcached server.
Are there any "gotchas" involved?

The cache keys are prefixed by the database name and table prefix (or more specifically, $wgCachePrefix or if not specified wfWikiId()), so if all wikis use different database names/table prefixes then there should be no problems.
