How do you use display specifications?

Question

The book "X Power Tools" has a chapter on "Display Specifications," which states:

Since X clients can connect to display anywhere on the network, it is necessary to have some way of specifying the display used. This is done using the display specification (or displaypec).

A displaypec takes this form:

      host:display[.screen]

How do you use specifications in your projects? Can someone connect to your screen if your host, display and screen are known? How can you protect it or share it if many people are working on the same project?
