well if you're talking about a panel where you ONLY watch a certain anime then i think that's called an anime viewing panel. You might have to possibly have a viewing license. hmm. if you bought the anime yourself (no pirate) then i think you are legally allowed to show it because you bought it. i think you may want to talk to the director of programming (for now i'm not sure who it is cuz we just had elections) so just email at this email: programming@kumoricon.org
i hope that helps
on another note, coming from a panel (KH) hostess. you should send in your panel request asap (once they are available lol) also PLAN plan PLAN! another thing, expect more ppl than you think may come (cuz that was the issue with my panel, not sure with others), and ask for at least 1 yojimbo to be there to help you with setup (electronics and stuff because i went to an anime viewing panel (hentai lol) and they had a computer problem and it took a while to fix, but because there was someone there who knew about computers, they were thankfully able to fix it more quick enough).
hope that helps too >.<
