[David Snelling]

Ian,

I want to answer these separately, so a few mails over the next few  
hours, as I should be pay attention in a meeting.

Later, I want to do a short summary of JSDL ant the same time and I  
still need to finish looking at JDL.

This is a simpler answer. I would leave delegation off the scope of  
this group simply to separate concerns.

Whatever the security mechanisms in place at the job management  
service, they should be composable with the job management interface. I  
know that some form of delegation is needed to manage the file staging,  
but a delegation service is not the only solution, so I am loathe to  
bind the two together is a specification. For example, the Unicore  
implementation would not require and delegation service. Lastly, if we  
need such a service, it should be done in the security area and be more  
widely applicable.
