unlikely, unless you build a statically linked executable.

yes, but you can then copy the binary you build to other nodes, which 
can save time.  If your program involves several files, you might build 
an rpm (redhat package), then install that rpm elsewhere.

I don't understand.  shared libraries aren't executable.  neither are 
object files.

no.

you execute what you want on a node.  the node handles no execution for 
you (except, I suppose, for rc.vinit, a script run when the machine 
boots).
