A system and method for delivering a document by a first computer to a second computer over a computer network. A method of the present invention includes the following steps: (1) decomposing the document into nodes in accordance with a document model of the document; (2) associating the nodes with a virtual layout space having one or more of regions; and (3) scheduling delivery of the nodes. Preferably, each of the nodes is associated with at least one region, and each of the nodes further includes one or more levels of resolution. In other embodiments, the method may include one or more additional steps such as, for example, (4) grouping the nodes in multiple batches each of which has at least one node. Preferably, one of the batches has all the nodes.
