Comment 9 for bug 35933

I think it is "standard in fact" on ircd servers enhanced with databases. This way, the passwords of nicks are saved directly on a main database or on a distributed database between ircd nodes (in md5, crc32,...). Then, when bot service's node fall down, authentication of nicks continues working (other advantage is that you don't need to send /msg nickserv identify pass to login).

I know this servers and this spanish networks:
ircu -> irc.irc-hispano.org
unrealircd+udb -> irc.redmundial.org

In irc clients, per example in mIRC, it is neccesary to configure your nickname as nick:pass simply (pass in plain text, sure).

To login, users type /nick nick:pass and then, /server irc-server
To kill ghosted nicks type /nick nick!pass and then /server irc-server

What do you think?
