You raise interesting points. The reason why there isn't better
support for removable devices is that the current resources didn't
allowed for more work to go in there.

I think Scott has plans to make possible run activities without
unpacking them anywhere, so I expect that would serve for your plans
of offloading activities to removable storage.
