Sidestream Versions
More recently, several irc daemons were written from scratch, such as ithildin, InspIRCd, csircd (also from Comstud), ConferenceRoom, Microsoft Exchange Chat Service, or IRCPlus/IRCXPro
These attempts have met with mixed success, and large doses of scepticism from the existing IRC development community. With each new IRCd, a slightly different version of the IRC protocol is used, and many IRC clients and bots are forced to compromise on features or vary their implementation based on the server to which they are connected. These are often implemented for the purpose of improving usability, security, separation of powers, or ease of integration with services. Possibly one of the most common and visible differences is the inclusion or exclusion of the half-op channel operator status (which is not a requirement of the RFCs).
