How to report on program member custom fields

Now that program member custom fields (PMCF) are available for our use, I'm curious as to how we can use these in our reporting?  They cannot be used in smart lists - when using smart lists to show a simple grid of member data - since that just uses data from lead records (when we want the data to appear in the grid).  They're not available in RCE - which is a shame, since this is where we do most of our reporting/analysis (especially using the Program Membership Analysis - you would think that these would be contained here by default).
