I think Marc Perkel's basic idea was implimented under CP/M as
a "user level." Also, the concept of a virtual directory structure
has been around about as long as "container files," such as those
on the old Intel MDS200 development station. This is hardly
"thinking out-of-the-box." It's just a rehash of some abandoned
stuff.
That said, a major speed limitation of directory lookups
is the manipulation and comparison of variable-length strings.
Maybe Mark might be able to improve this by truly thinking
out-of-the-box.
Cheers,
Dick Johnson
