Maybe you just don't have the right experience? (per your previous 
message) ;-)

A few years ago I worked on a TopLink system (ok not WO) with 
custom-built remote notifications that sustained a few thousands of 
database transactions *per second* at peak times. A dozen or so VMs 
updated the DB. An ability to keep multiple sessions accessing the same 
data in sync was priceless. If you have a relationship that is 
one-to-twenty-thousands, you can't afford to refetch it on every mouse 
click of every user.
