I don't think this would be necessary. For starters, you can always open a window on your browser and look at the live price. No point installing it on the forum. You're here to discuss, not to look at the prices.
Value of BTC is an important factor. I don't think it is hard to implement, if a user doesn't want it, he/she can turn it off in profile settings. Most probably, in Look and Layout Preferences.
Also chart buddy has got some good price info on his thread. You might want to check that out.
That thread is full of spam. It is better to look chartbuddy's post history than the thread.
