Hi. I am interested in getting a has for my small business. I need to backup a few machines, and would like to be able to share files remotely, and see if the file is currently being edited or used. (check out system) I know that the NetGear ReadyNas can do this when combined with the Egnyte software. Does anyone know if the Lacie 5big NAS using OS 2 can do the same? Also, can the NetGear readyNAS systems work on Mac?
