Open source software continues its torrid pace. In fact, according to a report from the 451 Group, the sector saw its biggest quarter for venture funding -- hitting $203.75 million, which is up from $100.4 million in the same period a year ago.

Why the interest? Well, I had a chance to interview Matthew Aslett, who is an analyst of enterprise software at the 451 Group:

Your take on the focus on open source?

VCs are interested in open source vendors because the open source development and distribution models reduce start-up costs and lower the barriers to entry. Some VCs have also cited increased code quality as a reason for investing in open source as the model enables a broader range of product testing and rapid innovation. There are a number of VCs that are sold on the open source model, and some have even stated that they would only consider investing in a software vendor if it was using and producing open source. Open source vendor revenues are lower than more established traditional rivals today, but most vendors are still in their infancy. Recent mergers and acquisitions involving open source vendors such as Zimbra, JBoss and MySQL have proved that the returns are there and are likely to encourage more VCs to look favorably on open source.

As one quarter rolls over into the next, here are some highlights from this past week's earnings coverage from BloggingStocks:

There's much concern in the information technology (IT) world. Might companies cut back on spending in light of the slowing economy?

Well, as for Red Hat (NYSE: RHT), the environment seems to be OK. For example, in Q4, the company posted a 27% increase in revenues to $141.5 million. What's more, bookings are bulging (above $200 million).

While RedHat has a strong business with its Linux offerings, the company is also seeing lots of traction with its middleware platform, known as JBoss. Interestingly enough, with Oracle's (NASDAQ: ORCL) buyout of BEA Systems (NASDAQ: BEAS), there's been a surge in downloads of JBoss. Basically, customers want an alternative.

Going forward, Red Hat forecasts revenues of $665 million to $680 for the upcoming year. Earnings are expected to range from $0.78 to $0.82 per share.

And Red Hat recently purchased Amentra, which is a systems services company. Basically, the deal will allow Red Hat to continue to turbocharge its sales of JBoss.

With the popularity of Facebook, bebo and MySpace, companies are trying to find ways to leverage social networking. However, it can be expensive to build out a strong platform.

Well, things are getting easier; that is, Ringside Networks has launched an open source server to build social networks (it's in the beta mode).

True, there are other systems on the market. However, in the case with Ringside, it allows for seamless integration with other sites, such as Facebook. In other words, it will help companies migrate users to their own platform.

What's more, Ringside allows companies to keep their own branding and the look-and-feel of their own websites.

Oh, and some of the co-founders of Ringside -- Bob Bickel, Rich Friedman and Mark Lugert -- were instrumental in the development of JBoss, which turned out to be one of the most successful open source projects in tech history.

To get some perspective on this, I talked to David DePaolo, who operates WorkCompCentral.com. He has known about Ringside for some time. His take: "It makes sense that someone would start this up as they have with other technologies, and just in time. As technology progresses, we find that it is not all about the technology and patents, it's the application of that technology to a specific market."
