I agree with you that the way guard/cred work is kind of neat, but it's 
kind of neat as a cooperative low-level primitive for building more 
full-featured systems on top of.  I can see the OP's point here: for a 
lot of use-cases, it's incomplete and you need to do a lot of extra 
work.  Work which isn't particularly well documented.

It would be really nice if we had more examples of *how* to build things 
on top of it.  If anyone reading this thread has some code to link to, I 
encourage you to share it.  Mantissa's sharing system is a good example, 
but it does a lot more than just wrap resources in a few simple 
permissions.  Also, as you say:
>unfortunatley, it is not a very well documented piece of software.

I look forward to your doc patches ;-).
