This may be a bit naive.... Is it possible to expand the RCMP+ spec
with a new cipher suite or similar, to use a mechanism more like HTTPS
or SSH that does not require the server to be able to produce a clear
text password? Given that IPMI will be used for many years, this seems
worthwhile, and would solve the current problem.
