To my understanding, this can get dangerous when you start to separate shared resources (e.g. lock tables) into different directories per instance. Once you start to access a database from several SC/CS instances, you might ask for corruption. See also: http://tracker.firebirdsql.org/browse/CORE-3268

Destination for the the temporary data (sort files etc.) can be configured per instance though. Check out firebird.conf.
