@andy_mc: this was a big deal a while ago as Warden (Blizzards sentry which searches for 3rd party apps interfering with the client) wrongfully flagged people running WoW through Wine on a Linux box as cheaters.
I've used the G15 keyboard all through my 3 year WoW subscription, and have had no problems with Warden.
It could be flagged if you use the G15's macro functions, where you can string together keypresses and bind them to the 15 customizable buttons, however just using the buttons to send weird key combinations to WoW is no problem at all.
For example, I use the first 6 keys in the upper left corner of the keyboard as mark macros when playing a tank in WoW. (G1 Skull, G2 Square and so forth)
