That's a neat idea, never thought of that.
But if a client releases it's lease (e.g. on shutdown), doesn't that break the idea by setting the lease to free ? Or does it retain it's "year in the future" end time and thus go a long way down the list of leases when it comes to finding a free one for a new client ?
