Would it make sense for an ISP to "store" the root zone on their DNS servers instead of letting it be refreshed by the 
DNS cache? A cron job could refresh it from time to time. It would avoid entries from expiring and would always serve 
to clients entries with max ttl?

A root server would be better, but that could be an intermediary step?

Just speaking out loud here, so it may be total non-sense...
