RE: a secure equivalent to rcmd() and rexec() ?

I need to send data to a command line on another machine, but
popen-ing an ssh
session seems like a rather inferior method, because there is
no way to
(portably) access the command's stderr...

not sure if this is the answer you want, but:
what if you tunnel the rcmd/rexec commands through an
encrypted tunnel? you could use pf and stunnel to redirect
traffic, maybe that helps. it's obviously not a development
solution but an administrative, maybe working one ;-)
