For the benefit of keeping and updating all modules in one place.

Imagine one node.js application running on a cluster of servers. Suppose you 
want to update it on every server. You can't just log on to all of them and run 
usual "mv node_modules node_modules_`date +%s` && npm install ." because some 
servers could be down (not mentioning that it's a waste of time). And things 
like "puppet" are too complex and require some scripting.

But you can have just one fileserver and update all modules right there. After 
that just restart all servers one by one (restart command could be issued with 
a database, no need to log in), and those down servers will magically use the 
new version when they'll start up.

I hope there's no need for synchronous interfaces because harmony generators 
will do the job. I wonder if fs.*Sync methods will become obsolete when 
generators will be stable.

So anyway, the idea makes sense. But I guess remote file systems are already 
doing this job just fine.
