My idea is the same as yours. 
But there is one problem. On RHEL5.0-beta2, a normal user (no root)
cannot run makedumpfile directly due to no path of /sbin/makedumpfile.
It is not secure to require a root login of a remote host to transport
a dumpfile. It is necessary to change makedumpfile directory, or run
/sbin/makedumpfile on a remote host:

# makedumpfile -S -cd31 -i /tmp/makedumpfile.config /proc/vmcore | ssh user at remote "/sbin/makedumpfile -R dumpfile"
