| firstly: does anyone know a better way to do this?

look at clusterit..

http://www.garbled.net/clusterit.html

it has as one of it's features;

Barrier sync for shell scripting.
    This is a new idea. The barrier mechanism consists of a daemon run on a
host, and a client which can be used to barrier sync with.

Not sure if it's suitable for what you want.
