Only semi-related: any news on the upstream Application Stack front? If not, could we start a small fundraiser to buy one of the CentOS developers a license to get access to the sources*?
It was decided to basically go ahead and push php updates without waiting for upstream to release, as php has some issues that need to be resolved, and are fixed in the new packages.
If/when upstream finally releases the web app stack, it'll go into a separate repository. The upgrade path from base/updates will be seamless. moving from centosplus to the web app stack repo will likely require manual intervention (removal of some packages with higher version numbers).
As to donations, everyone should feel free to use the 'donate' link on centos.org, as really this is how we can get some things done. I'm not sure how donations of rhn licenses are handled, so I'll let Lance or Johnny answer that part of the question.
