There are also very tricky details around "Extensions" (modifications, add-ons), where distribution of the main library is forbidden. As a last detail, the exception applies to given versions "or later, where the exception notice is present". As a technicality, the legal entity has changed names (to Sencha, Inc.), so the exception should be vetted for the "or later" part.

I'm less familiar with Ext GWT, but it effectively provides the Ext JS library to GWT apps, where I believe the binding is even a bit tighter.
