Abstract: An improved modular building panel and system for building construction is disclosed. The improved modular building panel comprises a novel honeycomb or lattice core comprising multiple layers of corrugated, preferably metal, components mechanically connected by any means known in the art, but which may be chemical bonding. External cladding layers comprising a novel cement mix comprising, in a preferred embodiment, Portland cement, silica sand, perlite, glass beads, and water, in combination with the honeycomb structure, provide a lightweight, highly durable, low-cost, projectile resistant, highly insulating, water, mold and mildew resistant, wind resistant novel modular wall system which is adapted for use in commercial, residential, and other construction and which provides superior security to the user. The modular building panel and system of the invention may be utilized for walls, roofs, floors, bridges, or other structures.

Abstract: A method and system for sharing files between a group of computer systems. The file sharing system allows a group of computer systems to be defined. The files shared by a group are associated with a group folder. A group folder is represented by a folder created by the file system of each member of the group. The folder at each member contains a file for each file that is shared by the group. The files in the folder of a member may be actual files stored at that member, which contains the content of the shared file, or virtual files identifying the actual file that is stored at another member. When a member accesses a virtual file, the file sharing system detects the access and requests that the file owner provide a copy of the file to the accessing member on a peer-to-peer basis. Whenever a shared file is modified, the file owner sends updated metadata for that file to the other members of the group.
