Actually it has more to do with multiple users being able to run
pulseaudio or esd. The 1000 happens to be your user ID on the system.
The next user account you create will have the ID 1001, and if this user
is in the correct groups and runs pulseaudio, his/her socket will be
at /tmp/esd-1001/socket. This way, both users can be logged onto the
system and have pulse or esd running at the same time.
