A linux/unix IRC daemon

Basically, I would like to know how much it would cost for a fully functional, feature rich IRCd which will be suitable for linux/unix based platforms. Or one IRCd which can me made into two version of the IRCd (ie Administration Server, client and hub server versions). ## Deliverables As I dont know ALL of the features I would like yet, I won't list them, as I am only after a rough guide as of this moment. ## Platform All Linux, Unix and BSD based platforms.
