We've written clipping plug-ins for a few specific apps that we figured would be used by the majority of OmniFocus customers. Examples include Mail and Safari. (There are also a couple of plugins that we wrote essentially for our own use - NetNewsWire and OmniWeb, for example.)

In other apps, we try to capture at least some information that would be useful no matter what the app in question was: the selected text and the title of the window that text came from.

Sounds like EagleFiler falls into that last category; I'll file a feature request for a clipping plugin for it. Thanks!
