Never mind, got it going.

It uses a very weird romanization style and input doesn't act like I expected from SCIM (or Anthy.)

For instance, to get 日 I have to type "niti." Also, it inputs showing romaji and tries to auto-convert mid-input instead of doing a swap once input is complete and I hit space.

I suppose I should look into an mscim/n900 port of Anthy, since it behaves more like I expect.

update:
It also won't activate in XChat, despite nothing being bound to ctrl+space :/
