noticed, it does not work out as well when editing shared files.

Oddly perhaps, Unix has never really provided shared writeable files. Perhaps there are good theoretical reasons for it; perhaps it was just one of those simplifying assumptions that Unix was born with, I don't know.

That's why access to shared writeable resources are controlled by a server, like CVS or svn or mysql. It's why you don't print using cat > /dev/lpr.

People seem to want to do things like this--they keep asking for applications to mediate between users editing the same file, like Windows does it, but I wonder if it's such a great idea.
