Questions on IP Interworking function in JunOS

While going thru the ARP mediation IETF draft I had a few questions
on JunOS IP interworking. In the past I worked on this but hadn't
thought of these until I read the draft. Can someone clarify these:

1. Does JunOS do only 'single sided ARP' mediation on an L2 VPN ? Is 
this what is covered in draft-kompella ? The configs that I did/saw so 
far required setting up ARP on the PEs that connect to an ethernet site
(when the far end is say frame relay).

2. Why should the operator manually assign proxy IPs for ARP mediation 
with JunOS ? From reading draft-ietf-l2vpn-arp-mediation this seems an 
extra work as compared to an LDP L2VPN. Is it not possible for the i/w 
function in the PE to do this automagically ?

3. How does JunOS handle Inverse ARP requests ?


Thanks !
