Actually, we have some sensor network folks that are interested in using OpenRTE for their applications. Their platforms can be small microprocessors, many with custom mini-operating systems. Almost none support IPv6 nor have any knowledge of that protocol.

networks of computers that may and may not support IPv6, and may and may not
support IPv6-mapped IPv4 addresses. In other words, the solution must support
systems including computers that only know IPv4.
    

It is clear to me that we cannot entirely rely on the availability of
IPv6-mapped IPv4 addresses. Getting the IPv6-enabled sources to compile
on systems without sockaddr_in6 or getaddrinfo() is sort of nasty, but
should be possible. For example, we could extend the configure script to
test this and provide some drop-in replacements in case these
structures/call are missing on the system.

Are there some reference platforms which are really old, but need to
be supported? The information on slide 101 on
http://www.open-rte.org/documentation/march-2006-orte/March-2006-ORTE.pdf
is fairly generic...
