Hi, good initiative. I hope it goes somewhere.
I've registered my personal instance (from where I'm posting), waiting for a guarantor now.
Small concern I do have for if this takes off: I hope there will be some way for personal or very small instances (with closed registration, for friend groups, etc..) to still get guarantors. I can imagine that when the web of trust gets big, it might be hard for personal instances to enter the bigger web of trust, especially to get guarantees from the larger instances. Any ideas or plans for how that might work in the future? A thread like this is already a good step, I was looking for something like this yesterday when I registered.
I have two of these switches, and after the first configuration you can also just change the management VLAN, so you can manage them from any VLAN after setting it up once.
