Good question.
I developed nuBuilder about 5 years ago. We decided to make it open source nearly exacty a year ago.
nuBuilder is quite a bit different than other open source products because we have developed this in house at nuSoftware, to use with our own clients.
I've done this for 2 reasons.
1-Its allows us to create/alter applications much much faster than from scratch.
2-I can switch a developer between projects or bring new developers on with a very short learning curve.
It has a lot to do with turning programming into a procedure (which is talked about in the E-Myth
http://www.amazon.com/E-Myth-Revisited- ... 0887307280)
The main reason we have made it open source is so that clients know that if they later want to host it themselves they can do so with out any licencing fees.
Neither are they locked into using us forever if they dont want to
(its a great selling point for risk management).
As you probably know we have video tutorials a wiki and this forum for anyone wanting to learn themselves.
We will be looking at training in the future as a revenue stream but will continue developing it for ourselves regardless.
Our latest release 10.04.20
http://sourceforge.net/projects/nubuilder/files/ is now avaliable (which added a bit of AJAX - when I first created nuBuilder there was no such thing as AJAX so I had to use invisible frames)
but we still have a long list things we want to add.
