This is a wery nice idea that I think is in the same spirit as the "intsalled images" in VMS. It also has a likeness with the ideas in Plan-9 but the other way around. In plan-9 everything is files, but the filesystem can be (and is) different for every process.

I think that I like the crossover idea of having every program that is runnable availible as VMS-like installed images, with the ability to
change the parts availible for each process. The two main parts that really need good design to build someting like this on is the security-subsystem and userlevel memory management.

I hope that this rather unstrutctured message makes some sence.
Also please feel free to correct any missunderstandings esp. reg VMS.
