Scripting Client Push Account Settings - Can it be done?

Greetings All,

I have a customer with a fairly large environment.  Security concerns require them to have a process to change the password on their service accounts that are used for Client Push.  They have Client Push enabled on all secondary servers (180) .  Is there a way to automate (using VBScript or PowerShell) to make a change to the passwords (i.e. actually changing the password or even a script to delete/create account settings in the Client Push settings)?

Thanks,

Brian
