VMware ESX Server to get InfiniBand support and more?

In a recent interview Diane Greene, VMware President, declared that Mellanox partner is putting InfiniBand support for ESX Server.

Are we going to see this on upcoming ESX 3.0? Or the next release?

On the interview another declaration is particularly interesting:
We’ll see where it goes. We’ll certainly embrace Xen if it gets to a point where it’s something our customers want to use. But it’s a long way from being in that situation.

What this means? I’d really like to ear your comments.
