Haven seen that. Just requests that _experimental_ features be prototyped
in ReiserFS, and _if_ they show they are worth the hassle, _then_ design a
nice VFS interface on them.

It is.

Dunno. That _you_ choose to do this is no reason _others_ will have to take
the results over lock, stock and barrel. 

Linux' development works because there is a lot of "wasted" effort on
alternatives that don't pan out. Many don't ever leave the drawing board,
others (like the (now defunct) Xiafs, devfs, and volume management code)
went far, even got fully implemented, only to be scrapped later. It might
just be ReiserFS' fate too..

Go tinker and play. But don't aggravate non-ReiserFS-users, please. Come up
with solutions to the issues Al Viro and Linus raised.

I'd guess LKML adds up to a few thousand years mulling over this, so this
isn't a great point.

I'd say it is a free world.
