Maybe. I said as much in my first posting. It's just that when a variable is
mobile, we specifically exclude (all right, simultaneous) sharing. But
having a shared cup doesn't imply simultaneous use by two people --usually. :-)
So perhaps I am wrong.

Does this mean that you want the abbreviation

x_mobile IS MOBILE x_shared:
to be
x_mobile IS SHARED x_shared: 
to match?

If we are to have a new keyword anyway, then it seems clearest to use it
everywhere. But I don't have any very strong views on this. Anyone?
