Mac OS and bluetooth proximity automatization

The colleague of mine started to look around on how to lock screen of Mac when he has to leave the computer. It is sad that there is no such easy solution for Mac as there is for WinTels. However among many interesting solutions there is one which is very intriguing - to use bluetooth enabled device to lock/unlock computer for you.
Here is a link describing the solution for Ubuntu:

Mac remote system pollution

Mac does pollute remote file systems it is mounted to by default. It spreads .DS_Store files all over them. I found a solution to prevent that.

1. In a Mac terminal a command needs to be executed: defaults write com.apple.desktopservices DSDontWriteNetworkStores true


2. Additionally samba can be configured to ignore those files. For each share defined in an smb.conf this directive has to be put in: veto files = /.DS_Store/
