Keeping abreast of Web technology presents a continual challenge to those wishing to provide on-line access to data: Java is not a panacea; JavaScript is needed to obtain the necessary interaction with Web browsers; VRML is surprisingly mature and has the potential to provide useful functionality for scientific data services. This talk describes our experiences with these and other emerging Web technologies in the context of our gridded data server -- the "LiveAccess" Server. Our server blends several technologies and provides a simple, configurable, data delivery mechanism for modelers and other suppliers of gridded data. The "LiveAccess" Server is freely available and is currently installed at institutions in a range of disciplines. Data available through "LiveAccess" Servers include hydrothermal plume model data, Martian surface data, European climate model data, ocean climatological data, tropical Pacific model data and recent satellite data.
