What you say is true to the extent that ExtJS has made it INCREDIBLY
ambiguous to decipher their verbiage. Basically what I have boiled it down
to is that you can use ExtJS at no cost as long as you don't distribute it.
They consider using ExtJS on a public website as distribution and so far all
of my coding has been intranet based. At least that is what I have been
able to decipher by emailing with the proxy person to their attorney.

Of the customers of mine that have eventual plans to use it on the internet,
after I show them how much value (i.e. time saved) ExtJS provides, well, the
cost becomes a moot point because it is reasonable based on time saved.

With all that said, my goal is to introduce a second "render kit" for RPGUI
that utilizes only LGPL and MIT licensed Javascript libraries (i.e. jQuery,
prototype, etc).

Never thought I would see the day where I had to understand legal verbiage
just to develop software. Interesting times we live in for sure.

let me remind you of, that Ext JS in it self are GPLv3 licensed and if
you uses any UX, they have seperate licenses - and they may be LGPL
licensed, but you will still be prohibited in commercial use.

So RPGUI also uses GNU GLPv3 components - and will NOT in a commercial
perspective be free !!!
