Systems and methods for rendering document-based user interface software objects are disclosed. User interface software objects may be represented in a document object model on a first computer system. These objects may then be communicated to a second computer system on which they are similarly rendered through use of a document object model on a second computer system. A document on a first computer system may also be updated to reflect either user input through a user interface software object included in the document, or changes induced by server side logic. The updates may be incrementally communicated to and rendered in a second computer system. Location-neutral user interface software objects may be developed without regard to whether the software object will ultimately reside on a client or server computer system, wherein the user interface software object is equally capable of being supported on either one of a client or server computer system.
