I need to create a Google Spreadsheet and share it with a set of computers connected to each other via a local network. Those computers are not connected to the internet. Is it possible to share a Google Spreadsheet between computers with no internet?

EDIT: I need a solution in which all the participants can edit the document simultaneously. Therefore I cannot just share a Microsoft Excel file. A magical format which allows simultaneous access and has the spreadsheet features will solve my problem.
