Spiking the ball to stop the clock and on TD's is okay. They are going to vote on assessing a 5yd penalty for spiking out of bounds. I found this clip from the St. Pete Times Forum:
"
The owners also will vote on Tampa Bay's proposal to use instant replay for all penalties except holding; increasing the number of players suited up for games from 45 to 47; and instituting 5-yard penalties for players who spike the ball on the field of play. Spikes in the end zone after scores would be allowed."
Here's another link to an informative article on the new discipline policy:

As image conscious as Goddell is, none of this is a surprise to me.
