Nope, the storage nodes are doing nothing other than mogstored at this  
time.

No I have not tried this.  Do you believe mogstored is pretty useless  
in a production environment?  If that's true and widely known, it's  
too bad the documents don't reflect this... Is there a document or  
list posting that explains what parts of mogilefs should be tuned (or  
outright replaced) for a high-traffic application?

Are there documents stashed somewhere that I'm missing?  I looked at  
the "new" wiki (last updates about 5 and 10 months ago) and read  
everything available there, and I've read most of the man pages.  I  
keep finding stuff that I'm totally not getting.  I would welcome some  
advice or pointers on how to get apache set up to replace mogstored  
for file transfers...
