Hrm... I think that's an inaccurate assertion.  And it seems like you  
probably missed some of the more interesting VMware features.  I'm not  
sure what you mean by 'full virtualization'.  I'm guessing you mean  
guests with unmodified operating systems.

Your initial list:

	- full virtualization (unmodified guests): GoGrid, ElasticHosts, and  
probably FlexiScale
	- shared block storage: not really sure what you mean... between  
hosts or guests???
	- thin provisioning: not a feature specific to VMware at all; doable  
with any reasonable backing store; many clouds already do this
	- high availability: VMware does this best, but FlexiScale already  
claims hot standby failover
	- VLANs: GoGrid and others
	- reverse ARP: what for?

Missed, but of particular interest:

	- memory overcommit: end user won't care, but worth mentioning since  
no one else does it yet
	- DRS: dynamic movement of live VMs based on resource/workload needs
	- dmotion: live migration of VM backing storage files; still mostly a  
VMware-only feature
