Not for a RG :-)

It could be populated entirely by graduate students doing interesting tests
in simulated environment using modified off-the-shelf (i.e. already RFC)
routing protocols.
And then writing papers, with the modifications written up as I-Ds.

I know RPL (RFC6550) quite well, and it has useful properties for space.
(Like, if a link-fails-in-the-forest, but nobody had any data to send, then
the link never failed).  I wouldn't want to use OSPF for this.

What it doesn't have is anything about motion: i.e., expected link failures.

I could see an attribute (a metric) which told of the sender's expected
motion, specifically towards or away from the receiver, and then this needs
to be correlated with occultations.   That would let the network do make-before-break.
I think that there are potentially many ways to do this; maybe it's already
been done.
