Can I connect a single Eggdrop to more than one IRC network/server?
No. Nor will such functionality be added to Eggdrop, because it creates a significant problem for commercial shell providers as well as administrators of private shells. The number of IRC connections a bot has is a major factor in determining how taxing the process is on the provider. Additional IRC connections do two things – take up valuable I:lines on major IRC networks (which can prevent others on the same shell from connecting) and increase the risk of DoS attack against the shell by creating additional targets. Allowing a single process to have a single IRC connection keeps things manageable. There is a bot, EnergyMech, which does have the ability to connect to multiple servers, but some shell providers have banned this bot because of this capability.
