I thought about this topic in the last two years manly (maybe because i am a dad of a 2 years daughter?).
Since already a lot of "cool" work i did in the past no longer is showable, or i even lost backups (DOS games, simulations, 3D games, startup failures, web frameworks) i guess that the same would apply to the current projects.
My conclusion was: as programmers we, at least, have to play the Museum Keeper role and consolidate our deliverables with proper VMs to show our software to our grandchildren.
Let's all hope VMWare stays solid and VirtualBox never dies! :)
