awk, hard to say where this might lead. I envision this as a way to standardize the management tools for an enterprise that is on a TPM implementation journey. From a trusted infrastructure perspective you are right on ... virtualization is a good thing.
I question whether a virtual TPM would secure a client as robustly as hardware TPM. In any event, it would be interesting to see how the Wave IP might apply to virtual TPM's. Not my area, but I would expect a lot of the client software processes and routines to be virtually the same.
