One thing that will need to be addressed for any long-term running application factory is credential expiration. Here are a couple options:

• generate a long-term proxy credential
• generate a long-term proxy credential and store it in the myproxy server. Store the myproxy username and password in a file and use that to renew the certificate whenever the cached proxy expires.
• generate a separate portal certificate and a passphrase-less key. Whenever the proxy credential expires, just refresh the proxy.
