Say I have a program being run on multiple computers all on the same network (and all on the same account). Every once in a while the program needs to read/write a file
save.dat. The actual file itself isn't important, more so is it's contents (just 3 seperate numbers that need to be kept track of).
As soon as the file is updated, the other computers should see that it has updated too. I.e. The program will read it and won't see that it is an old copy.
What way could I go about having these programs all accessing this constantly updating file? Perhaps some website (like pastebin)?
