I still need to address

A fix for this looks like it was already merged into trunk. It's not the prettiest fix but should work.
I'd also like to run some tests with composer and probably switch to
using an autoloader and not mangling include_path.
Other than these everything is indeed ready...
I'd like to switch o an autoloader but at least one stable composer release should be made with the legacy include-path option. There is a lot of legacy code dependent on HTTP_Request2 and getting everyone to update their usage to expect an autoloader is not realistic. This is an issue with the current stable releases on composer and one reason why I'd like to see a new stable release.
I propose at least the next stable release uses composer's include-path option.
