Forum OpenACS Q&A: What's the status of Zen for OpenACS?

We have a client with a 5.3.0 based site who wants us to do a new look. We'd like to base this on the new Zen layout, for future compatability. I have gathered from other threads that Zen was only implemented for dotLRN, but that some of it has already made its way into OpenACS, but I haven't been able to find any info on what the plan is for finishing it in OpenACS. Is this on anyone's radar screen? Is there any info anywhere on what needs to be done?
