Hi Rafael,
I share your interest! Over the last few months, I've been trying to gather more in-depth information on TeaTime and how it might be used in a different context, more geared towards distributed business applications.
Quite a bit of Croquet material can still be found, although most of the time it requires some cleverness with the Wayback Machine. However, I found it quite hard to get my hands on good TeaTime documentation and didn't dare to dive into the Squeak Croquet code yet.
Thank you for sharing the Archipelago paper, very interesting!
I came across this podcast recently. Haven't listened to it yet, but you might find it interesting:

Send me a PM if you're interested to have a chat about this sometime. I've been meaning to ask you about Blueplane.xyz for a while, but haven't come around to it. I'd love to hear more about your goals and share some ideas.
Kind regards,
