Remote follow don’t work as good as hardcore users would like it to. Federation mechanisms would have to have kilo- to mega-posts/second bandwidth but not happening.

Also that federation choice being in hand of instance owners makes an account on each instances a must. You are going to have a person or two that your instance owners don’t like, or instance or two that don’t like yours.

Curious – I run my own pleroma instance for myself on a tiny VPS and I'm seeing no problems at all, with remote follows or any other interactions.
