There should be dozends of grid implementations from various developers/companies used in projects by now. Something which might be interesting would be idea to build a grid utizling the drawing API and canvas tag in DHTML to speed up rendering.
@Max: have you done any performance test for grids when the cell borders are rendered using drawview and canvas? I'd be interested in working on an improved grid components which could be used on mobile devices with Flash & DHTML (Safari/Webkit/Android, etc.). Maybe someone else would be interested as well. Sebastian Wagner has - as far as I know - a custom grid component, maybe he'd be interested. @Sebastian? @Andy: what is the time frame for you for this improvement? I'd have time by the end of the year to work on that.
