IMHO, the questions are definitively valid for Nemo, even non nested. There are related issues being discussed at DHCPv6, for instance subnetting, that could be of some specific interest for Nemo. 
 
For Basic, I'm not sure if we include that?

Hi all.                               
Please consider the above picture. MR2 and MN2 on linkX want to establish a NEMO-network (consists of MR2 and MN2). 
It is assumed that MR2 needs to dynamically get a IPv6 prefix X for the NEMO, because the NEMO-network is created in an ad-hoc way.
When this new NEMO is created and attached to Internet via AR or MR1 the following questions arise: 
 
1.) Where will the IPv6 prefix for the NEMO be received from? From AR, HA or MR1 or some other network entity?
 
2.) What are the protocol requirements for IPv6 prefix delegation in a NEMO environment? 
 
3.) Do we need IPv6 prefix delegation for NEMO environment? The picture suggests yes, because no IPv6 prefix has been initially allocated for the NEMO.

Should these issues be concerned with in the requirements related to NEMO?
