	I'd be very happy with this approach.  We'd get our KISS
	which gets us our standard hardware someday & everyone
	could djinn up their own decorations.

	Would you also want to define some standard decorations
	together with some constraints on their behavior?  Or
	would decorating an interval take it out of 1788
	altogether?  I can see arguments both ways.

	We would also have to convince all parties involved that
	they need not lobby for their favorite features on the
	grounds that the decorations are available.  That may be
	a hard sell.

	But I like the simplicity of it all.  - Dan
