kind of laughing all the way home at this one since I frequently play an arranged version for violin at funerals:
Though it might be an idea for a possible ocremix. I remember a discussion a few years ago about whether a remix prominently featuring a vocaloid would pass the board; I think a judge piped in and said that as long as production and remix qualities were met, there's no reason that one wouldn't pass. I think the biggest hurdle people had was that they weren't confident enough in their japanese to make competent lyrics. Not having lyrics at all (or very simple lyrics) could bypass that limitation.
I should try messing around with the software again, for shits and giggles.
