I can second that.  I had several moderately busy production servers on XFS 
until ext3 solidified; not sure if I made the right decision to change.  XFS 
on Linux is very good, and the SGI folks behind it are very, very good. 

One does have to consider it's future considering the precarious finances of 
SGI, but that's another discussion.

JFS (at least under AIX; I dunno about Linux or OS/2) has a number of your 
wish-list features, if sadly not all.  It's also been around for a loooong 
time, relatively speaking, so many of the issues have been shaken out. 

Oh, yeah...and we can look at the code...:-)

I suspect that you could approach the JFS or XFS teams and look to negotiate 
a dual license.  They come from the proprietary world; they'll understand. 

RiserFS...dunno, and dunno if it would be worth it.

There is that...
