* Read the license terms for ExtJS to make sure you follow them. Unless 
you produce an application which you distribute under a non OSS license, 
ExtJS is GPLv3. No money flows.
* Do not confuse licensing of source code with the license for the 
things produced with that code's result.

* FLOW3 does not have ExtJS as a prerequisite, you could still use some 
other JS framework.

* FLOW3's license will be changed to LGPL, because GPL is of limited use 
for a framework.
* TYPO3v5 will be released under the terms of GPLv3.


PS: I am not a lawyer, if in doubt contact one.
