Welcome to the blogosphere. Nice first post. The model you refer to has also been referred to (not widely, although I use it in a forthcoming report) as Split Licensing (to differentiate from Dual Licensing). I'll follow up with more discussion later.

Andrew, thanks for the acknowledgment - I'm rather proud of what was created when I was with JasperSoft. I feel forced to be humble though - the concept of "visible source" for commercial extensions came from a panel I attended at OSBC one year, and then a couple of panels I was on at various events. At the original panel a buyer of open source (unfortunately I can't recall who) pointed out that the option of closed-source extensions was a non-started, since it eliminated most of the benefits of going with open source in the first place.

It was one of those "why didn't I think of that?" moments where once said, something seems obvious, but in fact wasn't. After that I had a series of discussion with folks at various events which resulted in the "visible source" (or in JasperSoft's case, "modifiable source") for commercial extensions.
