Backbone offers varying degrees of access to remote workers.
The most popular method for most clients now is to have thin client access via a remote desktop connection. The user experience will be virtually the same to that of when they are in the office both in terms of the look and feel and also the speed of access.
Users will be able to access any application they wish from their CRM, accounts package to a MS Office application.
More traditional forms of remote working are still used including dial up services establishing VPNs over broadband or 3G access from a mobile data card.
