Right, I think everything is working well now. I call up the tunnelkeepalive script from within another one, then when that one has finished doing what it needs to do, it deletes the LOCK file thus stopping tunnel maintenance and then disconnects from the vpnc.
otheus thanks for your help - really appreciate it. I never realised that by defining a variable in /var/run/ it would be assigned a pid. While this is a bit off-topic - are the other .pid files in /var/run/ dynamic i.e. if one were to kill the pid in that .pid file that .pid file would disappear?
