PHPCMS was acquired by Ku6.com

As everyone knows, Ku6.com (http://www.ku6.com/) is a Web 2.0 video-sharing site, while PHPCMS is a CMS platform mainly providing content management for websites, which is the core of a website. So, what does Ku6.com's acquisition of PHPCMS mean?

Are video sites not doing well, and is Ku6.com looking to transition?

Is Ku6.com acquiring PHPCMS's development team to reduce operational and development costs?

Is Ku6.com using PHPCMS's market share to promote video advertisements?

Aside from these, I can't think of any other reasons.
