Not likely
"This 6094 line card sports 44 ports running at 40GE and 176 ports running at 10GE if you use the four-way splitters on it. This new line card will be available in April and costs $36,000."
No way is that accurate. First, if you take the newest Supervisor offered, you are looking at 80Gbps of fabric bandwidth per slot. 44 * 40Gbps is a serious over subscription rate. Four ports would be 2:1 which is doable, what is not is 22:1. If the traffic is going between ports, sure it works, but as soon as the fabric is needed, there will be problems. I highest over-subscription I would expect is 4:1.
I could see getting 44 ports on a 6513 chassis with 11 of these cards (assuming 4-ports per card), but not 44 ports per card.
