The management of application and experiment software represents a very common issue in emerging Grid-aware computing infrastructures.The current solution adopted by the LHC Computing Grid (LCG) infrastructure for HEP experiments allows an Experiment Software Manager (ESM) to install the software on a VO-specific file system shared among all worker nodes (WN) of a farm.With this work we present a more flexible service based on P2P technology that has been designed to tackle the limitation of the current system.Here we illustrate the design, deployment and preliminary results obtained.
