You'd send him your script, not your remote.ini, where the variables are.
Anyway, how about:
Code:
on *:LOAD: {
  set %nofirstrunofmyscriptname $true
}

on *:START: {
  if (%nofirstrunofmyscriptname) {
    ; first run stuff
    unset %nofirstrunofmyscriptname
  }
  else {
    ; whatever else
  }
}

Sidenote: I ran the posted script on v6.21 and got a 'no such identifier' error, as $sha1 was only added in v6.3
Changing it to $md5 worked, tho.
Perhaps you have Windows Scripting Host disabled? (I seem to recall once having something that would do that.)
