Patented, eh? Does the patent holder explicitly allow third parties to read and write to that part of the proprietary MP3 file format, or can we expect them to pull a bait-and-switch down the road like CompuServe did with GIF?

They are already pulling. MS, Apple etc pay them royalties now and anybody reading and writing to and from the file is expected to do the same. They have attempted to go after some of the freeware tools and have gone after several smaller commercial developers.

Take a look here:

and here:

http://mp3licensing.com/

Note that this covers tags and playing and the creation of MP3 files. Ogg is a good substitute though Thompson GMBH have turned their attention to that as well several times in that they suggest Ogg *may* infringe on their compression patent. Another company in the USA had Microsoft in court in February as they also claim to own a patent on MP3 (not sure of details of the actual patent held) and wanted mega bucks for use. They won and MS are appealing. The tags are covered by the Thompson patent but getting precise details requires you contact their lawyers. Having done that once I'd not recommend it - they are creeps. <g>
