log rendering in real time in audit-viewer

Hello Miloslav, and all the guys! We use audit-viewer for events monitoring. Unfortunately, if some log is rather big it takes to much time for audit-viewer to parse and render it. Besides, we need to render log updates in real time, i.e. when a new line appears in a log, it should appear in a viewer too. Can you suggest the better way to extend audit-viewer to meet these requirements? Thanks in advance. Kseniya Muratova,
