A while back I had proposed to Antonio the concept of using IUP to create web forms. The idea was that one code base could cover both desktop and browser environments. There is member on the IUP list that is willing to help with this effort. I would like to use Script BASIC sbhttpd server to prototype the HTML IUP driver.
There has also been good progress made with the Cocoa driver for OSX.
