Found an interesting addon Druid Helper (http://www.curse-gaming.com/en/wow/addons-4239-1-druidhelper.html)
Hmmm, looks interesting! We'll have to give that a try :)
About that class channel one have to use to broadcast the messages; hope it can differ from people inside and outside your raid (e.g. RG1 and RG2), so that we don't need to set up another channel for it. Think I'm closing up on the max-channels limit pretty soon ;)
lol blizz really needs to up that limit by a few channels, 10 max, 4/5 go to standard channels, then class channel, CT channel, nef counter channel, thats 6/8 and i got the dutchy and channels for alt class => 8/10 full house nearly, depending on addons running
