AquaMinds, makers of the popular NoteTaker, has released NoteShare 1.0, a "powerful desktop application for creating, publishing and sharing media rich, multi-page notebooks." NoteShare allows you to "instantly" share a notebook for presentation or collaborative editing across a room, a network or even the web. Interestingly, their product page states that you don't even need hosting space in order to publish and share a notebook.
While NoteShare sounds like an interesting product for its target users, AquaMinds is a little slim on details as to whether NoteShare represents a new level of note taking and rich media abilities above and beyond their NoteTaker product. However, since NoteTaker sells for $70 and NoteShare is priced at $150 for a 3-machine license, I'd bet the premium price is all about that collaborative ability, rather than some fancy new note taking features. If all this notebook sharing business has your interest piqued, AquaMinds offers a 30-day NoteShare trial; just follow the link on the right here.
