So with Merge Modules and Concurrent Installs being officially dead and evil, and each new Microsoft product needing to integrate the experience of deploying more and more reusable components, it really comes as no sup rise to me that Microsoft is finally tackling this issue.
In the "Agility Trends in Packaged Software" white paper by Robert Flaming (MSFT Windows Installer Program Manager) one little section caught my interest:
Your tools vendor may be your first choice in your Better Together path and could even be your conduit to spectrum of software providers that want to provide you a Better Together experience on their software.
We are in a bold new world, and there is a lot to digest in the white paper, but I'm already wondering what kind of standards will be established ( ICE's, Logo Certifications ectera ) to help ISV's develop micropackages that can easily be composited into a Better Together solution. I also wonder if tools vendors like InstallShield are really the best candidates to establish these practices as it could cause problems when multiple ISV's try to integrate their packages and find out that they are somehow incompatible due to design reccomendations from their competing tools vendors.
I really don't know how this will go down yet.... there is alot of information that has been shared privatly with tools vendors yet deemed to secretive to share with actual front line setup developers. Maybe 4.5 will have a strong enough contract that this problem is mitigated and maybe it'll be too loosely defined as to have the innovation come from the tools vendors and lead to exactly this contract.
Either way, if you find yourself supporting installation stories like I described, or if you see yourself selling software that might be consumed by ISV's that support this story, you really owe it to yourself to start reading over MSI 4.5.
