Hi Jeff, I'm Nicola, the Ceo of wpXtreme. First of all thank you for your deep review and your feedback. Let me now comment your doubts.

About the wpXtreme plugin dependency, this is actually a mandatory aspect because of some components embedded in the wpXtreme framework. The feedback about the sunset clause it's great and we will add it to our website pretty soon.

To be true, if we were to go out of business, the downloaded plugins won't stop working, maybe only the store and the plugin/themes updates (as all the plugins on the wordpress.org repo). This is the same for every plugin/theme maker that stops its activity.

About Bannerize and Cleanfix, it's true what you said, but the plugins on the wordpress.org repository are working (only bannerize has some bugs, and we will release a newer version on the wordpress repository soon). Unfortunately, at the moment we are only a few people in our team, so it's very difficult to pursue business and our opensource passion, but we work hard to do it at our best.

Regarding the need of downloading wpXtreme as a barrier we will soon release the possibility to download single plugins/themes directly from our website and then get wpXtreme with just one click.

I know that our goal sounds (and it is) hard, but we believe it could be a good plus to the WordPress community and developers. I really hope that your prediction will be wrong! ;)
