Hmmm the rfc1812 title says "Reqs for IPv4 Routers" (not hosts)...

Are MANET Routers referring to RFC1812?  BEcause RFC1812 says:

To me that reads that if a device has a single interface then it can't
act as a router.

Also rfc1812 says:
> An Internet router performs the following functions:
[...]

Since MANET is so vaguely defined, because of the undetermined link
connectivity properties, one wouldn't say that a MANET Router is an
Internet Router.

WEll.  There are file systems and dynamically compressed file systems.
There are off-the-shelf kernels and home-brewed re-compiled kernels.

Few things are pure :-)
