Subtree proxying using the same security information

[Majdi Abuelbassal]

Guys,

Is there a way to allow agent (A) to proxy a subtree from a different
agent (B), 
but using the same security information that used to get/set other
subtrees from 
Agent (A)?
The way it is setup now, you need to use different security information:
either
different v1/v2c community name or v3  different engineID. At least
that's the
way I understood it from docs and code.

Majdi,
