I feel too :)

I don't have any resources to grub QCPatch design cause that is not
publicized by Apple ;)
Everything I know so far is a collection of lots of web searches and
observations of QuartzComposer behavior.It seems the QuartzComposer
framework collects all ports by their names (prefixed by input/output)
when a QCPatch instance is initialized.

Anyway, If adding/removing ports at any runtime is available by some
API, that will be enough for me. I will try digging more.

Cheers,
