It's an interesting problem.  In order to make ExtJS part of a web
application, you have to distribute it.  The web application needs to
comply with the terms of the GPLv3 because it is combined with a work
under the GPLv3, to create a larger program (by virtue of hyperlinks,
they are also not separate).  However, the whole web application is
not distributed, only part of it, so it's rather unclear what the
GPLv3 means in this context.
