Sharedance is a high-performance server that centralizes
ephemeral key/data pairs on remote hosts, without the
overhead and the complexity of an SQL database. It was
mainly designed to share caches and sessions between load-
balanced PHP Web servers. Access to a Sharedance server
is trivial through a simple PHP API and it is compatible with
the expectations of PHP 4 and PHP 5 session handlers with
no code change.
