Here's an article about adding up to 12 digital channels to a single FM carrier:

Keep in mind that what you linked to is a press release and not an actual article. The idea is interesting, but one glaring problem jumped out at me immediately. The additional sidebands for 96.3 range from 96.0 to 96.6. It seems like the second adjacent signals at 95.9 and 96.7 are going to get clobbered. I think we've already seen this movie with AM IBOC. I would love to know what the effect was on the in town KFDG-LP at 95.9 was during this test.
