Abstract	The LHCb grid software has been used for two Physics Data Challenges, the most recent of which will have produced 90 TB of data and required over 400 processor-years of computing power. This paper discusses the group's experience with developing Grid Services, interfacing to the LCG, running LHCb experiment software on the grid, and the integration of a number of new technologies into the LHCb grid software. Our experience and utilisation of the following core technologies will be discussed: OGSI, XML-RPC, grid services, LCG middle-ware, and instant messaging.
