Nice snippet overall. The dialog could\'ve been a bit neater or at least spread out a bit.

Also:

menu channel,nicklist,menubar {
  [Bioshock-Away]
  .Away: dialog -m BioAway BioAway
)

Should be:

menu channel,nicklist,menubar {
  [Bioshock-Away]
  .Away: dialog -m BioAway BioAway
  }
}

Again, nice work. :)
