The "Net Neutrality" issue -- whether or not companies like Google and Yahoo should have to pay the big telecom carriers to ensure that their services are delivered in a timely fashion to consumers -- continued to dominate chatter at Brainstorm.

Stephanie Mehta already has posted about how a conversation on Thursday about the cell phone revolution turned into a debate about Net Neutrality. Christopher Sacca of Google said he feared what would happen if "the people who own the networks can make choices on what customers can or can't see" and added that even though Google does not always see eye-to-eye with its online rivals, Net Neutrality is something that Google, Yahoo, Microsoft, eBay, Amazon and IAC (which owns Ask.com and many other online properties) all agree on.

But former Motorola CEO Christopher Galvin, who at first said he was unaware of the term Net Neutrality (a confession that was met with some snickers in the audience), argued that network providers should get paid back for their investments in broadband infrastructure.

This debate spilled over to Friday morning's breakfast panel discussion about where VCs were putting their money. Morgan Stanley Internet analyst Mary Meeker sided with the Internet giants, a stance that did not please the woman sitting next to her, Citizens Communications CEO Maggie Wilderotter.

Citizens, one of the nation's largest telecom carriers focusing on rural markets, obviously has a stake in how the Net Neutrality debate pans out. Wilderotter conceded that AT&T CEO Ed Whitacre is probably taking too antagonistic a stance against companies like Google. But she, like Galvin, said that phone companies have every right to "monetize their networks."

Stay tuned to see how this all pans out. But based on the conversations at Brainstorm, expect this to be a highly contentious battle between Internet behemoths and the telecom titans for months to come.
