That's strange. I asked them if they would do a "pig vs. bunny" panel (for those who don't know, Shinsen's Vincent has a bunny "Yuebing") and they said it would be fine as long as I hosted it. I asked them what if PETA showed up to protest and the response was lit. 'f*** PETA.' But it's a moot point, I won't go to that con, much less host a panel, I've never gone to any con outside of my own city, so don't expect to see a "pig vs. bunny" panel if you do show up.
Fansubbing, esp. digisubbing, is the black sheep for these things. Even if there is a demand, they're under pressure from the industry to _not_ have anything like this or promote it in any way.
