I recall we agreed to increase the maximum lifetime to 72 hours.  This has been the case at the CEDA myproxy service for a few weeks now.  I have tested PCMDI's service and it only issues certificates for 1 day.

I'm not sure whether the most recent java webstart app allows you to set this.  I hope PCMDI and other centres will deploy the 72 hour maximum lifetime soon.  Would this meet your requirements?
