WordPress is free there. There are a lot of OpenSource programs available for install on their servers.
As for plug-ins... write your own or have them written. Just php... and from what I have read, WP is the easiest CMS to hack so.... making plug-ins should not be hard.
400.00 a mo for OpenSource software? WOW!!! I must have missed something in this post.
