Mate :: Flex Framework

I have been hearing really good things about Mate for a few months now.  I have been rebelling against dragging additional frameworks into Flex just for MVC for a while now (Flex and MVC /  Cairngorm).  I finally got a chance to spend some time coding with Mate on a flight back from San Fransico this weekend.  I think it looks promising.  I am still not sure the leverage is enormous, but the cost seems low.  It appears to provide a reasonable structure for Separation of Concerns and managing events, without requiring much additional code.  Hopefully, I will have some more time to do something more complex soon with it, but I think it may be the type of framework I have been wanting.
