What exactly would need to be added to Bitcoin to support Zerocoin?

Question

I have read some information about Zerocoin, but not the actual paper.

My question is - what exactly would need to be added to Bitcoin full nodes in order to implement it?

Just the special "zerocoin mint" and "zerocoin spend" transactions? Are they some special, non-standard transactions?
