How to use the Clip-O-Tron from OmniFocus 1?

Continuing the discussion from Overall, how are you liking OmniFocus 2 relative to OmniFocus 1?:

New sandboxing rules prevent OmniFocus 2 from installing the Clip-O-Tron, but if you use OmniFocus 1 to install the Clip-O-Tron it should work perfectly with OmniFocus 2.

(We don’t intend to make you keep OmniFocus 1 around forever to do this, so we’re contemplating putting together a separate installer package for it which customers will be able to download from our website.)
