WRT my merging plans for libv4l. I've recently done some much needed work to better support high-res usb cameras. I plan to do a 0.8.4 release with that work included real soon. Once that is done I'll change the version in the Make.rules to 0.9.0-test and merge the plugin. Then we'll have some 0.9.x releases followed by some 0.9.9x release (all testing releases) followed by a 0.10.0 which should be the first stable release with plugin support.
