Me neither.
The most obvious distinction between the title of a proposal and its ID is that the title is assigned by the proposing astronomer(s) and the ID is assigned by the observatory acting as an agent for the resources the astronomers are proposing to use.

A name, including a shortname, applies to a resource - whoever assigns the name. A catalog, instrument, telescope, filter, etc., is a resource. A proposal is not. A proposal can ultimately result in the production of a resource, such as the catalogs or images published by a survey project. These may themselves have a shortname - a nickname - that might colloquially also be applied to the project or even the proposal.
For example, Nick Suntzeff is the P.I. for a proposal entitled: "The w Project: Measuring the Equation of State of the Universe". NOAO assigned the ID "2002B-0007" (see http://www.noao.edu/perl/abstract? 2002B-0007). This has resulted in a survey - and the fruits of that survey - also known as "ESSENCE" (http://www.ctio.noao.edu/essence). One might then choose to refer to the "ESSENCE proposal abstract" (a casually assigned name), for instance, even though the acronym came about after the original project was proposed.

Agree with this, but this distinction is only the result of who assigns the token. A name can be assigned by any party involved in some resource transaction. An identifier may only be assigned by the holder of the resource.
