Tilghman just made a few changes that I'm excited about. I had some ideas to continue that work.
I want to add context to manager accounts so that we can limit the originate action for each manager account.

With Tilghman's patch, we can filter out events based on channel variables. Maybe that can be extended to channel lists in the future.

I would love to continue this development work.

And btw, we have manager/TLS now.
