I have now played extensively with Plexer and found that it does once and for all solve the problems with boxing on a Mac. I played against bosses where I SPAMMED the hell out of my keys to ensure that all my toons kept casting, and then any time I needed to move or jump or anything, it did just that. It kept up with my key presses. Like most broadcasting, when you spam too much some presses get lost here and there for whatever reason, but it doesn't LAG. If a key press is lost it's not because the program couldn't do it. I know that Plexer doesn't have all the features of other programs, but it's so simple to use that I almost prefer it. I do use Keyclone on my PC when I 10 box and need 2 computers but I have fewer issues with Plexer right now.
