The clients I use have ZNC integration. I use Textual on OS X and Colloquy on iOS. Both automatically play back the buffer when they connect without having to do any setup like perform scripts or whatever. I also compiled a module for ZNC that sends push notifications to Colloquy when a PM, highlight word or name mention happens.
