Thanks Simon. However, that doesn't permit the use cases described above. The CIDR algo of upstream-user-ip could be a contrib/ script for a general-purpose upstream-user-ip-cmd?

Let the outgoing IP/hostname ("localAddr") for upstream connections be determined from user info at dial time.

Example implementation: https://git.sr.ht/~mooff/soju/commit/42dcf362

Alternatively, a script could be run, passing e.g. username as arg 1

This lets an admin setup "vanity" hostnames, split users into e.g. staff.foo.bar; plebs.foo.bar, or even e.g. username.foo.bar (possible with reverse DNS delegation)

Fwiw a scenario is described here[1]i

Hm, can this really happen? If so we should clarify it in modern-irc. A timeout would be good to have regardless.

I wondered if there's a timeout for the queuing mechanism - it's not guaranteed that a WHOIS command will generate a response, e.g. when the upstream queries remote servers

Also, it's just cool.

With no account, we connect you to our IRCd as ~username@cyberspace.baby.

Registered, you're username@cyberspace.baby, and can use BOUNCER to connect to other networks.

Motivation is to explore federation / identity based around that.

But, I thought appearing as foo@chat.sr.ht to other networks would be useful for your service, too.

For access lists, bans, knowing who you're talking to, etc.

Running cyberspace.baby with:

652c247f Set upstream usernames to user's username by default

d1a45fb2 Send usernames over ident, accepting privacy reduction

Bouncers are where usernames are most useful / meaningful, imo.

The current version was tagged was last year, making it hard to tell if distro packages include more recent fixes like:
