"Restricted" and "Unrestricted" are attributes of the VSWITCH, not the 
user.  If the VSWITCH is unrestricted, then there is no access list and 
all users can couple to it.  If the VSWITCH is restricted, then there is 
an access list and only those users in the access list can couple to it.

Based on what I've read here and input I've received in other venues, I've 
concluded that, for non-ESM environments, the access list is the set of 
all users who have a NICDEF (not SPECIAL!) statement in their directory 
entry that references a particular VSWITCH or Guest LAN, *plus* the users 
identified on SET VSWITCH GRANT.

No additional authorization is required, but they will not show up in 
QUERY VSWITCH AUTH (since no GRANT issued), nor can the authorization be 
revoked by command.

Uncoupling from the VSWITCH doesn't hurt.  If you COUPLE again, it will 
work (a la LINK).

All of the above applies equally to a restricted Guest LAN.
