Jackpot Share

I won a share of the UltimateBet jackpot about a week ago. I was sitting at one of the $0.50/$1.00 Limit Holdem jackpot tables and someone at another table (but at the same limit) hit it so everyone not at that table got $260 and some change, which in terms of the limit we are sitting at is ... well it's 260 big bets. The bad beat of this story is that I wasn't sitting at more than one table (which I usually am) because you get a share for every table you are sitting at...

I've been playing quite a bit of low limit Holdem at UB the last few weeks and trying to improve my multi-tabling. So far the most I can do halfway reasonably is about six tables and that is without paying all that much attention to individual players. It just blows my mind that there are people out there that multitable 20 tables at a time. I'm wondering how that works, exactly, as I'd have trouble hitting 20 different buttons when it is my turn to act...
