Don't be a fool, Avici is no Juniper Networks. Their Terabit router does no good but heating the room. Those East Coast telecom-centric companies simply don't have a clue on how to build a good IP equipment.
Keep your money in CSCO or JNPR if you must invest in router companies and forget this loser!
There are lots of comments BUT most folks really don't understand AVCI's true potential. AVCI has unique pattened technology that is amazing....the AVCI routers will create a new paradigm for data transmission. Big players (like Enron Broadband and Williams Communications) are close to making some major purchases from AVCI.
CSCO and JNPR are GREAT companies but the REAL UPSIDE is with AVCI....once they get the big orders watch out....;-)
