No, not any more.
Actually I did implement that capability several years ago, where you
could build a remote "crashd" daemon that you could connect to in order
to access dumpfiles or /dev/mem on a remote system. But it languished due
to lack of interest and the preference/speed-superiority of using NFS,
and so it has long since been deprecated. The code still sits there in
the sources, in remote.c.
