If you were really serious about putting this gem of a product to widespread use, you would get busy doing the following:
1. Make the client free to download for all Windows 7 users
2. Make App-V available like Hyper-V currently is (licensing and cost)
3. Initiate a vendor partnership program to offer incentives to provide sequenced applications, maybe as part of a subscription "Fast-Track" advantage program.
4. Actually get behind the whole program instead just paying lip service.
