I'd like to hear back from anyone with an opinion on this. What do you think of as the ultimate bus after PCI and why? 1. Hypertransport 2. RapidIO 3. Star Fabric 4. PCI Experss 5. Infiniband Any others that will be players? I get asked this sort of question all the time and I need some new material. :) Alan Deikman ZNYX Networks, Inc.
