Hi Eric!  Nice to hear from you.

Well, a valid and good reason for having the queue local is
that the LDM just won't work otherwise.  The queue is a
memory mapped file.  Memory mapped files don't work across
mounted file systems - the memory mapped file must be on a
local disk. 

If your sys admin doesn't buy this, he could always write a
little test program to confirm it.

Hope this helps!

Anne
