Yes, you can.  We have a large number of servers at our divisions that
all need to send us files.  They all use the same key.  It would be
best for each to have its own key, but they are run by an outside
company, and tar -xzvf stuff.tgz;./install.sh was a little complex for
them even.  Generating their own keys would cause a brain melt.
