Interesting idea!

You're right that it probably wouldn't get integrated into the official
pidgin-otr, but you're also right that plugins can't really modify other
plugins in the way you want without other cooperation.

What you're envisioning is an "authentication plugin" architecture
for the pidgin-otr plugin itself.

Definitely an interesting idea, and hopefully not *too* ridiculous.
There would need to be some kind of signalling mechanism for
registering/unregistering authentication methods at runtime, and some
specification for what such an authentication method might entail.

The various suggestions of GPG, DANE, etc. integration could also fall
into this framework, I would think.

I can't put this on my own plate right now, but I would definitely be
interested in seeing a discussion on this list, leading to a git branch.
