option - because win2000 does not support any temporary memory based file
system.
Not so.

It uses exactly the same algorithm. It is just that the hash

You might discover that a memory based database has few advantages over
a disk based one, since Sqlite uses cacheing and the OS uses virtual
memory file cacheing. The main difference might be initial accesses
being slower while the cache fills up.
