Vonage is reportedly preparing for an IPO according to the WSJ.

According to the WSJ, Vonage is planning an initial public offering to raise as
much as $600 million. According to the article, "Citing a person familiar with the matter, the newspaper said Vonage had already raised more than $400 million in venture capital from firms
that include Bain Capital, 3i Group Plc and Institutional Venture Partners... There was no immediate comment from the Edison, New Jersey-based company, which declined comment to the Journal."

Makes you wonder if Google Talk was the "spark" that made Vonage start the IPO ball rolling now. Or it could simply be coincidence.
