Network mounts work fine for this kind of thing. I don't usually do it
with binaries, due to architecture and library incompatibilities, but
I have a directory that I mount on half a dozen systems, and part of
what it carries is a Python script. So in that sense, I do run that
program from one central machine, on all those other machines. I use
sshfs for the mounting, but other systems work too.

Of course, it is a dependency. In my case it's safe, because the
purpose of that Python script is bound up with the rest of what's
available (and which must be centralized; it's about a terabyte of
stuff, and I don't want to be constantly syncing it). It all depends
on how dangerous that is to you.
