PHP sessions in a load balancing cluster - how?

Question

OK, so I\'ve got this totally rare an unique scenario of a load balanced PHP website. The bummer is - it didn\'t used to be load balanced. Now we\'re starting to get issues.

Might be too late, but check this out: http://www.pureftpd.org/project/sharedance

Sharedance is a high-performance server to centralize 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 a pool of 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.
