The datastore will be getting support for versioning to deal with  
this scenario properly.

Well, broadly speaking, the security model is a non-problem for most  
activity authors. You're attempting to do something unusual (in XO  
land, so far) without considering how our security works, and it  
doesn't surprise me that this has been causing you pain. This is  
partly also our fault, since there isn't a document summarizing the  
(long) Bitfrost spec and its implications for casual developers. I've  
CC'd Mike Fletcher who might be the person to write such a primer.

I'd invite you to answer my previous e-mail about the concrete use  
cases where dealing with the security system is "too much" for you so  
that we can see how to best resolve the issues.
