Sflow billing or usage calculation software

Thanks for the pointers and suggestions!

Now I know I'm pushing my luck... but do certain vendors more fully 
embrace sFlow than others? maybe one of the whitebox vendors if not one 
of the majors?

Hacking support into something isn't the worse thing in the world, but 
if there is any experience on this to leverage off of, that is helpful.
