Drawbacks of extending Magento guest session maxlifetime?
===

We are interested in extending the session duration for guests that visit our Magento website. By default if a guest adds an item to the cart and leaves the page afer 24 minutes the session is destroyed and when they return the cart is zeroed. I extended the maxlifetime via htaccess to 6 hours to test it out and it works correctly. I know my manager is interested in keeping sessions alive for 1 week or even longer. My question is: what are the potential drawbacks of keeping sessions alive this long? Server performance, server space for session files, security concerns, etc?
