Skype says business users grab 30 percent of its downloads, but is the enterprise ready for wider use? \n\nThere are many good reasons why Skype is slowly making its way into the corporate world: Its free, and you can forget about country codes, telephone numbers and long-distance bills. With a mouse click, youre talking, or even video\u00adconferencing, with any of the 170 million Skype users worldwide. But there are also good reasons why corporate IT views Skype skeptically. For starters, it can be a bandwidth hog. Another problem: Most security products dont yet monitor Skype traffic, meaning that Skypes file-transfer capability may make an end-run around your companys firewall. Now Skype is vying to address these concerns.\nConsider the case at Holly Corp.: The petroleum refiner blocked Skype outright when it first noticed employees sneaking the software onto the corporate network two years ago. We started noticing that bandwidth was not available, says Paul Sheth, network and systems lead with Holly, in Dallas. And before it started causing a problem that people would notice, we blocked it.\nUp until recently, pulling the plug was the only way corporate IT could control the software, but lately eBay, Skypes parent company, has been jazzing up Skype so that people like Sheth will take a second look.\nIn December, eBay released a new version of Skype that gave outside programmers some level of control over the software, and those changes are already making Skype easier to manage. For example, FaceTime Communications now sells software that can be used to centrally control which Skype features are permitted on the network.\nWith FaceTime, Holly can turn off videoconferencing at regional offices with low bandwidth, or block file-sharing with Skype.\nStill, security remains an issue: Sheth says he still doesnt quite have the level of control over Skype that he wants. Its making a stride in the right direction, he says. As far as mass acceptance, it will still be another year or two off.
