The plugin is loaded with Acrobat/Reader. Plugins are not apps to be invoked, rather they are a collection of callbacks. you have an initialisation callback, which regusters the others. Don't think of Acrobat as being a command line with a file on it. Acrobat starts. At some point file(s) are opened. If you registered for suitable call backs (like PDDocDidOpen) your callbacks will be called. In any order, any number of times. You can register an Idle procedure too, which gets a callback when Acrobat is idle.

I don't think there is any possibility with the command line. You can invent your own way to communicate with your plug-in if you are careful with these rules.

1. A plug-in cannot stop and wait for events in the main thread without blocking the app.

2. A plug-in can create new threads but must not use any Acrobat API whatsoever in these new threads.

The very simplest approach would be to create a file in a known location which the plug-in looks for. Be sure to identify the target file, as your plug-in may be called for other PDFs, including invisible PDFs used internally, and PDFs shown in external windows. Subject to the above restrictions you can create COM servers or other kinds of IAC.
