Hi Roald,
Not sure about that (I'm not a lawyer, fortunately), but I think
changing the license will be very difficult, considering the usage of
ExtJS. But I'll ask.

Hi Thijs,
The license incompatibility (GPL v3) may become an issue if code gets
used from your project. Is there any way you could contribute the
relevant code to OpenLayers (which is under the 2-Clause BSD license),
provided that C2C wants to incorporate your code of course?
Thanks, Roald

Hi Eric.
In the Netherlands we have Web accessibility guidelines. For a
project (called GEOZET) in which these guidelines are very important,
we have made some changes and additions using ExtJS. So I'm not sure
if that is okay with you as well. I haven't been coding myself, but
code can be found at:
https://github.com/geozet/geozet. The dir ./src/ contains javascript
code.
Added functionality for accessibility includes:
- another PanZoomBar, that is accessible using the keyboard. For code
see:
https://github.com/geozet/geozet/blob/master/src/Geozet/lib/Geozet/widgets/PanZoomBar.js
- a new renderer, for vector points, in HTML. This way the popups are
also accessible with the keyboard.
- sorting of features in the map, so users can use Tab to go through
the features on the map from left to right, top to bottom.
The "alt" attribute is not used on the map images though. Don't
remember why we didn't do that.
The final result is not online yet, but the code is open source. If
you'd like to see a working demo (with slightly data in it) in
action, I'm hosting one here: http://nieuwsinkaart.nl/geozetnijmegen/

Hi devs
Some of us at Camptocamp are currently extending an OpenLayers
application to make it accessible [*]. For this work we need to modify
OpenLayers in a number of areas. Here are the features/modifications
we are considering:
- navigate the map with the keyboard when the map div gets the focus
(currently the KeyboardDefaults control works with the document only)
- make the panel buttons accessible, by using appropriate markups
(<a>+<img> in place of<div>)
- add "alt" attributes to<img> elements
We'd like to avoid duplicated effort, so we're interested to know if
others are working, or have worked, on making OpenLayers more
accessible.
Thanks,
