+ Where to go next

We started with Trond asking if we wanted to concern ourselves with a Smart
Server at all. Eventually, the point was raised that Smart Servers imply Smart
Clients or someone could copy a file on the dumb client. This may be handled
by site security.

David provided this taxonomy:

Dumb - can't spell Label
Label aware - passes/stores object labels, calls back label changes on open files
Semi-smart - Implicit or explicit subject label for the client. Could set once. 
Fully-smart - Subject label per compound - i.e., per users or process on the client

Peter wants us to focus on just the protocol and not the security aspects. We
agree, except the security models we support impact the protocol support.
Tom stated that LNFS is not that complex and we may be trying to refine it too much.

We had consensus in the room for David to provide a high overview of
how a semi-smart implementation could work, i.e., do we need an op,
to the WG alias. There we will drive towards consensus.
