Topic: Block Reactor

[SPDCad]

What is the best way to redefine a block with code?

I am in the process of creating a lisp reactor that monitors blocks and if the block creation/change date attribute has change the block is redefined in the current drawing.
So therefore I want to redefine the block without actually inserting a new block when the reactor is called.
The reason for the lisp reactor is to bring all the power of dynamic block to an Xref, well sorta. 

Any help is appreciated.
Thanks in advance.

P.S. If anyone has some object reactor lisps and is willing to share some code, I woudl be grateful. For this is only my second object reactor, so I am still a rookie with them.

I think this one over on the Adesk Ng is pretty much what you want to do, and was talked about pretty recently.
