	Not particularly unusual for large NFS server installations I've seen.

	And this works today?  You don't have file locking problems, etc...?

	Fair enough.  I wasn't aware that anyone was doing this sort of 
stuff today with NFS, and that this worked without all the 
traditional file locking problems, etc....


	Certainly, I'd agree that we should support PostgreSQL and 
MySQL/MaxSQL, BerkeleyDB, etc... as alternative database methods that 
should be included with the base package.

	Now, whether one of them should be the primary database method, 
I'm not quite ready to agree to that, at least not yet.  I tend to 
place pretty high value on the "Keep It Simple" style of solution, at 
least as far as the default stuff is concerned.

	If SQLite is easy to install, gives us decent performance, 
doesn't make it too difficult to replace with alternative database 
solutions, and satisfies our other criteria, then I'm all for that. 
In that case, I'd rather we spent more time providing hooks that 
would allow us to swap out the database back-end for something 
faster/more robust, as well as doing things like fixing the 
pipermail/archiving tool, archive searching tool(s), etc....


	Out of curiosity, can someone remind me where the current mm3 
"wish list" is?  Are there mm3 specification and/or design documents 
yet?
