Welcome back to Baby Breakerdom! This week's quest to find budding Rule Breakers turns up another firm joining the battle for Internet telephony supremacy and a Baby Breaker that just might make global financier George Soros drool.

We begin with SunRocket, which is looking to grow its share of the massively popular voice over Internet protocol (VoIP) market. That it lags the heavy in its space, Vonage, by at least 700,000 paying customers matters little to management. Nor investors, apparently. VentureWire reports that the firm secured $25 million in its latest round of financing, bringing total funding to $34 million. The capital, it seems, will be used to help SunRocket buttress its network -- there were notable outages in July -- and fund aggressive expansion as the presumptive low-cost leader in the space. Indeed, SunRocket offers a rule-breaking $199 all-inclusive annual deal as well as a monthly option that matches Vonage's rock-bottom pricing. I've my doubts it will work, but that doesn't mean old-line telcos like Qwest (NYSE:Q), SBCCommunications (NYSE:SBC), and Verizon (NYSE:VZ) shouldn't be really worried. They should be.

Next, we move to the wild and wonderful world of currency trading, where Soros has famously made and lost billions. New York-based Oanda, which provides a technology platform for trading currency over the Web, has decided to tap the private equity market after nine years in operation. The company raised $17 million in its first round. Oanda told VentureWire that it has been profitable since 2001 and that it has grown by "a factor of three" over the last four years. Sounds like a Breaker in the budding to me. I only hope it doesn't end up as the next eSpeed (NASDAQ:ESPD).

Finally, in Baby Breaker public offerings, Ikanos Communications (NASDAQ:IKAN) broke the IPO dry spell Thursday by offering 6.4 million shares at $12 each. Shares in the company, which makes chips for Internet TV, gaming, online file-sharing, and video conferencing, closed at $13, up 8% from the offering price. Not bad for a day's work, eh? It remains to be seen whether the company, which is unprofitable, will be able to emulate the performance of rival NVIDIA (NASDAQ:NVDA), a member of the Rule Breaker Universe (get access here, or take a free trial).

That's it for this week. See you back here next Friday, when we continue the quest for the next ultimate growth stock.
