The @germnetwork.com team has been participating in the #e2eemessagingWG to figure out a way to have secure private group messaging that is compatible with ATProto.
They've shipped a proof of concept of using your account to do this!
You'll need to get on the waitlist as they slowly add people.

Have fun.
I am reminded of TOPS20 on Kingston Poly's (then new) DEC 2060, in around 1980 (because that was the year I had my first slow melt-down over study stress for my A-levels, and took refuge in the Poly's computer lab on my school account).
