Being able to provision over point-and-clicks does not get away with the 
rest of the configuration. I know you can do  (depending on the EMS) a 
certain types of security configurations. Personally, I haven't seen an 
EMS capable of do a very good hardening of the configurations of DSLAMs 
and CMTS's.

1) Point out? I know but I can't. This is a public list and I would get 
fired if I discuss in public anything from a client with name. But 
believe me when I say _it does_ exist.
2) Well with a over subscription you can do it on the Junipers E Series 
(and I've seen it).
It is on the technical docs of the ESeries but you can also see it in 
this URL: (http://www.thinkjuniper.net/isp/information.asp?page=239)
3) It is not a configuration I will ever recommend; but sometimes due to 
budget restrictions of what a provider set to spend for the servicing of 
a location, the provisioning division just "make it work" doing this.
