state or future of LFS?

Dear List readers and netbsd devels,

what is the current usability state of the LFS (Log-structured File System)? 

Is it ready for productional use or still to understand as under development? 
Is there any active roadmap? 

Did someone have practical experiences (stability, performance, handling...) 
with LFS within productive environments? Are there any other interesting 
alternatives under NetBSD? 

Did someone played or worked with other filesystem alternatives for large hard 
disks (i.e. some cluster FS's a.o.) then the default FFS with interesting 

I'm using NetBSD 4.0 and 4.99.73 (and sometimes other *BSD's) for different 
productive internet servers (i.e. email servers) - under xen and wo - on SAS 
based disk RAID's (10 and 5)  and my idea is to use / switch over to a LSF 
for my larger email-storages. 

My main target's are:
 - fast recovery (i.e. after a crash / power disruption)
 - fast file access (i.e. mail space under cyrus imap)
 - minimized data losses after crash or medium failures

There are different infos about the roadmap and the current state of LFS 
around in the net - like here:
or here

many thanks for any hint o tip in this issue and - for you all here -
have a nice easter-weekend,
