In a post from PHP Magazine today, there's mention of an interesting discussion that was had at the latest NYPHP meeting concerning the accessing of the NDB Cluster native API directly from PHP.

With the Cluster API, retrieving data is easiest as lookups on primary keys. This structure would make the NDB Cluster an excellent session storage handler for PHP -- fast, reliable, and makes sharing data across load-balanced web server machines a snap.

Also, there is an offer he makes to anyone out there looking for an interesting PHP/C++ project to work on: "I think Hans (http://hans.zaunere.com/)and Johan, both from NYPHP, would be happy to help out anyone who wanted to work on this (PHP/C++ coding project)".

It definitely seems like a project such as this could have some very nice possibilities...
