User-configurable channels

Hi,

Thanks for this wonderful module.

I am implementing revenue sharing in my site using this module. I would also like to track the performance of my ad blocks, using channels.
However, When i use the channels using this module, they get used for all the ads irrespective of the client id.

Since the channels are created per account basis (by google), i guess, My channel id may not be used when displaying an ad with someone else's client id.

The hook adsense provided by this module currently only supplies client id. can it be customized to give channels also ?
