An idea on nick-collisions

[ircd@xxxxxxxxxxx (Kaspar Landsberg)]

Hi all,

i've got an (IMO nice) idea on how to prevent nick-collisions. The idea  
could replace nick delay (ND) but it could also coexist with it.

Currently (i'm talking of irc2.9.?), if a nick-collision occurs, both  
users get killed and have to reconnect - which creates some extra-traffic  
(server-to-server and server-to-client).

And now my idea: If a nick-collision occurs, ircd simply changes the nick  
of the two users who collided!

Example: User1 (Kasi) is on server A, user2 (Kasi) is on B. A (re)connects  
to B and a nick-collision occurs. User1's nick is automatically changed to  
"Kasi-" (or "Kasi\", "Kasi1", "Kasi]", etc.) and user2's nick is changed  
to "Kasi--" (or "Kasi}", "Kasi0", whatever resembles to "Kasi").
And both users get a server notice (something like "Automatic nick change  
due to a nick-collision.").

If ircd can't find 'quickly' a new nick for both users (already in use),  
it can still KILL them (which will almost never happen i suppose - depends  
on the implementation).

That solution would be much more user-friendly, save bandwith and it would  
almost abolish 'hostile' nick-collisions. [And if it replaced ND, it would  
also save some memory... :)]

What do you think about it?

Bye, Kasi
