I tried (and failed) to make packages for these two. Cannaserver is a kanji server, that enables you to get kanji with Japanese input. Kinput2 is an input editor, allowing you to input Japanese.
Someone (opti?) made a canna package, but he'd made a few goofs in packaging, so it didn't stay. He wound up, IIRC, going on to a different distribution, so I can't ask him for it. :-(
