[saga-rg] Re: SAGA and Security

[John Shalf]

I don't know if this will help or hurt the discussion, but has  
everyone had an opportunity to read the ACE-grid security document?  
It refers to itself as addressing security for "collaborative  
environments," but they go through a number of use cases that are  
very relevant to SAGA.  Deb Agarwal and Markus Lorch also contributed  
an excellent discussion of implementations and scenarios for  
reasonable security implementations .  It may help bring us SAGA  
members up-to-speed on some aspects of the security model  
considerations.
