I am working on a SF project which will required some mobile devices for remote data.  This application is for a company that provide appliances repairs services for refrigerators and stoves.  The database MS-SQL will be hosted in an ISP location.

These will be the basic needs:

• Tech Reps on the road will need to have access to a pre-define service route list and when a service is provided the customer will need to sign the order sheet (electronically) as an acceptance of the job.
• The device most have live access to the database since the route list may change at any time, so this most be a live connection.

Couple of questions for SF Team:

• Can SF be used to develop the Mobile Device application?
• If not, could it be possible to create the Mobile Device application as a Web application? so it can be access online from the Mobile Device.  Still I need a way to capture the customer signature for an completed work order.

Please anybody with some kind of experience in this regard willing to share some information will be greatly appreciated, including any idea, even if it has a different path than the one outline above.

Thanks in advance!
