If you want a true password policy for all your network elements you might look at an Access Control Server. Since you are already committed to using telnet to access all your routers to change your passwords this might be the perfect time to consider TACACS+. Please read the following for an idea of what I am talking about.
"The Cisco Secure Access Control Server (ACS) Solution Engine is a highly scalable, 1-rack unit dedicated platform that serves as a high-performance access control server supporting centralized RADIUS or TACACS+. The Cisco Secure ACS Solution Engine provides a centralized identity networking solution and simplified user management experience across all Cisco devices and security management applications. The solution engine helps to ensure enforcement of assigned policies by allowing network administrators to control:
* Who can log into the network
* The privileges each user has
* Security audit or account billing information
* Access and command controls for each configuration's administrator."
