I'm considering setting aside the compute resources to host some small salon-sized (say 16 user) instances to see how well they develop.

I would be willing to set up and host ~10 of these as an experiment, and would commit to both operating them for at least a year and to making them as easy to move as possible should a particular salon decide they'd prefer to self-host.

I would like to offer either postActiv or Mastodon servers for this at the salon's choice.

Would there be interest?

To be clearer, this would be a "bring your guests" situation - I would not have an account on each.

I would also expect you'd bring a (sub) domain, although I have a few domains I could offer a subdomain on if a group needed one.

Okay, there's plenty of interest it seems.

I will start putting together some infrastructure and some clear terms of service, etc. and get my ducks in something approximating a line and then I'll figure out how to get people set up.

I'll document the setup so others can play with similar structures beyond my ability to foot the blood sweat and tears ;)
