There is a fairly significant difference from the performance perspective.
In the extreme cases:
Per-pipe charging encourages the pipe-purchaser to run it at 100%.
The supplier, conversely, wants to run it at 0%.
Byte-charging encourages the purchaser to run at 0% and the supplier
at 100% (assuming the supplier is actually making a profit on the bytes :)
The second scenario is, IMO, more likely to provide better performance to
the data that runs across the pipe...

utilisation %-based charging is another word for byte-charging, too :)
The only thing 'wrong' with volume-charging is the fact that current
volume-charges (when expressed in c/M) are probably an order of magnitude
more expensive than when the same data is bought 'by-the-pipe'. Go figure.
