Opensource router takes on Cisco

As I had written in my earlier posting about voip and open source and its impact on telecommunication network equipment business I would like to present another example that proves my earlier posting .I was reading this article in redherring I would recommend its worth to read it.
In short a start up called Vyatta is providing open source based router sw bundled on standard server HW from dell. For those of you who have been working or associated with telecommunication business know how radical this change is compared to the present models and practices.Ofcourse this wont make Cisco out of business or infact effect thier bottomline immediately ,but it is one clear trend if continues and gains momentum like it happened in pure SW area, then we may expect drastic change in business environment .Initially atleast this startup is targeting at small enterprise were this product suits well.
