neatroff VS hyperswarm

I recommend sticking with Groff. There are other implementations of Troff—some older (Heirloom Doctools), some newer (Neatroff)—but most of the documents you'll encounter in the wild will have been written with Groff in mind.

Plan 9 troff might work! It works with utf8 out of the box[0], and while I haven't used it for complex math typesetting, there is a command (eqn [1]) that was developed for it. I'd recommend Ali Rudi's port (neatroff [2][3]) for a minimalist implementation. There's also Heirloom Documentation Tools [4] which is an implementation of *roff-and-friends that uses Knuth's paragraph-at-once algorithm (instead of the original line-wise one) for typesetting, plus some other interesting features.

The authors of eqn wrote a paper about it: "Typesetting Mathematics" by Brian Kernighan and Lorinda Cherry. Kernighan also wrote two manuals (one in 1976 with a revision in 1992, and one in 2007 with updates for the Plan 9 version). [5].

[0] utf8 was developed by Ken Thompson and Rob Pike during the creation of Plan9. The entire OS is compatible. Story here: http://doc.cat-v.org/bell_labs/utf-8_history

It took me a minute to realize this, but HyperShell seems to be (or can be thought of as) a demo app for the (previously unknown to me) "hyper ecosystem"---Hyperswarm, Hypercore, Hyperdrive, etc: https://docs.holepunch.to/ . Perhaps an even tighter example than HyperShell is hyperbeam [1]: look at the usage section and API, and then note that it's all implemented in like 200 lines of code.

I'm no expert in this field, but this stuff looks like legos for cutting-edge P2P solutions. I think this is the coolest thing I've seen since Tailscale.

Thanks for all of your great questions!   We're using Hypercore protocol which uses something called Hyperswarm to connect peers over DHT/Kademlia. What's really neat about a Hyperswarm version that was released is you can create a firewall and whitelist specific public keys of peers that are allowed to connect to you. If a peer is not whitelisted then no exchanging of IPs happens.   We've also thought about eventually adding a mix net like I2P over the network for added anonymity.

With things like Hyperswarm [0], building things like that is easier than it used to be
