create a table formatted like you have in your xls file and create a simple webpage to view the data in real time. You could upload the xls file to start exactly where you guys are at now and even create and export to spreadsheet feature if you need it for reporting etc. Should only take 2-3 hours to set everything up the way you want it.
My first thought was Sharepoint but that's also provided you have a Windows box to put it on and not just *.nix based servers.
