vConsolidate definition was based on market data that outlined what application types are being consolidated in a data center. Market data here means information gathered from market research (e.g., IDC), end-customer feedback and various OEMs / ISVs.
We have heard that there are two consolidation usages. One you can call it to be homogenous application consolidation (e.g., file servers) and the other one to be heterogeneous application consolidation, and vConsolidate uses both. The advantage of homogenous application consolidation is from a manageability perspective, where all the applications exhibit the same behavior and the IT administrator has a better understanding of how to manage the environment. vConsolidate use case represents SMB (Small-Medium-Business) environments where they can gather their applications on a few machines along with the environments. Once the applications are consolidated, they employ VM migration technology for load balancing. With VM migration, the VMs are migrating around the data center where at any one instance you will have a mixture of VMs on a physical platform. Market data shows this is a growing trend in the data center.
Looks like you are aligning with our stated advantages of consolidation mentioned above. Your use case is Test and Development which is also another consolidation usage. We believe that the future would be heterogeneous application consolidation where folks will become 'comfortable' with the notion of mixed workloads. This is the value of vConsolidate, where we can address the concerns (e.g., QOS). BTW, all the VMM vendors are supporting (or planning to support) this migration technology.
