I agree with the belief that the user should be able to get help.
Why is this the system administrator's job? Why shouldn't the user be
able to say, on a case by case basis: for this problem I would like help
from Jim or Jane?

Through control over resource allocation -- which is accomplished by
setting up the space banks and the scheduling conditions.
It seems to me that we are fighting with a deeper issue here. In order
for freedom to mean something, users *must* be able to establish privacy
from spying. We agree that the user needs to be able to get help. It
does not (and I would say, *must* not) follow that we must introduce
architectural support for spying and privacy violation.
