Using MEF as an IoC

After reading some stuff such as this: http://mikehadlow.blogspot.com/2008/09/managed-extensibility-framework-why.html

I understand that MEF has some featcures that I will not find in an IoC, and that MEF has some IoC stuff that is probaboly not as advanced as some other IoC systems can offer.

I need the MEF stuff. Do I also need an IoC framework or would I be fine with what MEF has?
