We provide enterprise-level patch capability by enabling customers to add/patch a layer in an incremental way without removing 2moons gold or replacing the original layer. At most, this is accomplished by allowing administrators to deploy delta bits to the PC where the original layer or application resides. For those that package applications, this eliminates the need to repackage applications each time there is a change or update and also allows for the delivery of an original package, along with a number of delta packages or patches, to a machine where the software has not been deployed previously.
