I don't think an ALL-glheþ broadcast is necessary or possible, but just one in which we show off the pronunciation of some commonly used words. I don't know if you were watching, but the Leader of the Opposition pronounced "Ziu" in two different ways in his rebuttal, lol.
It should be a live dialogue at best, because honestly I don't know whether you guys pronounce the same way as I do. (I remember that I always used to pronounce the O in Talossa in the same way as in English "loss" until I was forcibly corrected.)
