The Workplace strea of software appears to be the future from IBM. From the next release of Notes and Domino it looks like that client will merge with the Workplace client. I’ll stick my neck out (probably get shot down) but it looks like the humble NSF will get a much reduced role and in my view probably become a feature of the new client for backwards compatibility.
Workplace itself, like most modern collaboration products, is a combination of integrated technology so to demo it and look at it yourself can be difficult. IBM have a good site here with screenshows demonstrating the new products (link). There is also a 3 day online demonstration for Workplace available here.
