Hmm the other way round is easy enough,
scp jhary at 10.0.0.10:foo.tar.gz /dev/stdout | tar -ztf -

and either way with full ssh
tar -zcf - * |ssh jhary at 10.0.0.10 "cat > foo.tar.gz"
cat foo.tar.gz |ssh jhary:10.0.0.1 "tar -zxf -"

I hope some of this might help as i cant think of a way to do as you 
want.
