  I think yes. It doesn't seem obvious why an Internet Draft should go to 
expire: Is the topic sufficiently discussed or is the draft insufficient 
... And a comprehensive problem statement gives a good starting point for 
further work.

  What does a universal P2P overlay protocol mean in detail? Is it similar 
to the common API by Dabek et al. ("Towards a Common API for Structured 
Peer-to-Peer Overlays", 2003)?

  Btw: It makes sense to have an interface definition between ALM 'stack' 
and application. But this should be a part of a common group membership 
framework maybe borrowed from IGMP/MLD. That could be also an outcome of 
SAM RG.

  Or in both - like the approach in OverSim which allows to incorporate 
real-world traffic into the simulator.
