The designer client is now free, but to build web apps you still need a server and notes license. I would propose a 10 user server (maybe use the Lotus Foundation) for little or no money if they build a web site. They would get a 6 mnth trial license and if they built a site, then it would be a permenant license.
It would allow small design/development firms to get into Domino development.
It could be a web only server.
It would allow individual developers to build Domino apps and have a server to host their work on.
