There was one in gentoo a while back with a -g option... It got removed from cp source since someone didn't like it.

Man I'm a nerd.

I usually just background the cp and ls -l the source and destination files. Not as pretty, but it works just as well.

'scp <user>@localhost:<src> <dst>' works reasonably well when I need it...

Wouldn't that be much slower than using cp?

I suppose it would depend on whether or not 'cp' would find itself disk-bound in the same situation.
