Have I gone completely insane? There is a PHP .NET compiler called PeachPie. other than dependency issues, I might be able to compile the #pterotype plugin when it becomes a library into a .NET assembly. That way, there's the implementation for .NET #ActivityPub. @jdormit@mastodon.technology, so you know what it is I'm referring to, look at https://peachpie.io. Haven't played with it yet, but have decided to pursue PHP and C# at the same time.
