How to Combine Castle ActiveRecord entities with normal NHibernate entities?

I am trying to integrate entities defined with ActiveRecord and entities mapped with plain-old .hbm files.

I need to have associations between the two, i.e.:

ActiveRecordEntity.HbmEntity

&

HbmEntity.ActiveRecordEntity

The only thing I've bumped into that seems at all related is the ActiveRecordMediator but it didn't look like it would support this case exactly开发者_运维百科.

This isn't implemented (yet!). See this question for more information, it's the same case.
