Why not lobby Congress ourselves?

I have my occasional disagreements with Kos, but something he said sparked an interesting idea.  In thisdiary, he sayeth:

Remember, we don't have the millions to compete with AT&T's lobbyists, and our best-crafted arguments can be easily ignored. All the while, Steny Hoyer buys loyalty by tirelessly campaigning and raising money for his fellow Democrats. So how can we overcome those obstacles?

Along with funding primary challengers, why doesn't the netroots start a lobbying arm of its own?  If Hillary Clinton and Barack Obama can pull in fifty million dollars a month, surely we can come up with enough money to match anything that AT&T, Verizon, Altria, or Big Pharma can furnish.

Imagine how we could emasculate Hoyer and the rest of his cabal if we could put more people on the ground in DC than exists in all of K street.
