If you’re an ISV working with IBM Lotus Notes/Domino, or if you’re simply trying to sell applications built on Domino technologies, then The IBM XWork server sounds like a great idea in terms of licensing.
I can think back to many of my past Domino clients (because I don’t really work with it much anymore) who would have had use for this, and a couple of instances where it would have made a lot of discussions around justifying costs/an investment in Domino much easier. It’s something that could have had a lot of relevance in the New Zealand marketplace where “small business” means something quite different to the rest of the world, and where some discussions around the cost of IBM technologies often ended up badly.
A little late for those scenarios, but maybe it’ll add hope for the current breed of Domino Developers.
(Actually, do they even call themselves Domino Developers anymore? Are they XPages developers now?)
