Can you force Eggdrop to change nicks?
I've never tried it.
I'm guessing you could probably set the bots default nick as etari, then if it's in use, it will go to an alternate nick.
Then, you could probably have it execute .restart every time it finds "etari has quit IRC".
Only problem is, I don't know if Eggdrop sees quits the same as you do on mIRC.
# Set the nick the bot uses on IRC, and on the botnet unless you specify a
# separate botnet-nick, here.
set nick "Lamestbot"
# Set the alternative nick which the bot uses on IRC if the nick specified
# by 'set nick' is unavailable. All '?' characters will be replaced by random
# numbers.
set altnick "Llamab?t"
