+# tabssh
+
+[idk](https://twitter.com/rsnous/status/1365106287080472579)
+
+Uses [TabFS](https://github.com/osnr/TabFS) and
+[gilderlabs/ssh](https://twitter.com/jf/status/1352012743600062465).
+
+Set your TabFS mount path in `tabssh.go`.
+
+```
+$ go run tabssh.go
+```
+
+and
+
+```
+$ ssh -o StrictHostKeyChecking=no localhost -p 2222
+```
+
+(you can set a fun hostname in `~/.config/ssh`:
+```
+Host last-focused-tab.safari.localhost
+    HostName localhost
+    Port 2222
+    LogLevel ERROR
+    StrictHostKeyChecking no
+    UserKnownHostsFile /dev/null 
+```
+)
+
+## ideas
+
+a hack would be to make it dispatch to tab depending on provided username, like how
+[their Docker
+example](https://github.com/gliderlabs/ssh/tree/master/_examples/ssh-docker)
+dispatches to process (ssh `jq@localhost` runs `jq`)
+
+but really, the _right_ way to do it would be to make it so that
+`safari.localhost` is a hostname that actually lets you talk to
+Safari, and `last-focused-tab.safari.localhost` is a hostname that
+actually lets you talk to the last focused tab.
+
+could you make a virtual network or something to do that? (where each
+tab is a host on the virtual network) I mean, that feels
+philosophically right; [tabs are virtual
+computers](https://twitter.com/rsnous/status/1352014584731734016), so
+maybe they should be network-addressable like your real computer is
+(and maybe other things should be network-addressable that way too --
+individual applications, documents, etc).
+
+like 'port numbers' feel kinda like they unnaturally promote one level
+of computer, the physical one on your desk that has a Wi-Fi chip, and
+hide the computers nested inside it (such as each of your browser
+tabs)
