A friend of mine, Simon Shapiro, has worked for years with the Unix kernel to overcome the limitations of the sequential search in Unix directories. He has created a b-tree index as the directory built into the kernel capable of millions of entries with instantaneous access to any of them. This would have been great for UniVerse as a type 19 file or UniData DIR file. Unfortunately his health is failing and this research project which he hoped to market is dieing with him. Anybody interested in picking it up?
He is actually a little late. There are a number of alternate file systems for various Unix platforms. XFS and AFS are both out there. The most ambitious is probably "ReiserFS" (http://namesys.com). This is a btree (while, sorta btree) object oriented file system. We have users with Universe running 500K directory type files (dont ask) under the older reiser3 with good performance.
There is life past ext2.
