Will an open source router replace your Cisco router?

Vyatta is an open source company that hopes to take the XORP (i.e., extensible open source router platform) and make it a commercially viable, enterprise-ready product. Pronounced "vee-atta," Vyatta wants to do for routers what Red Hat did for Linux and what Asterisk is trying to do with VoIP. (For some background, see George Ou's blog post, "Open source routers shine at Vyatta secret society.")
