I'm interested in developing an client-side application that can load Word documents in-browser using the Office Web Apps service running on a SharePoint 2010 server. The application would be run on a tablet, and all the client would provide is the desired document name, which would then open in-browser via Office Web Apps.
If I provide the proper directory and login credentials, is this something that could be done entirely through a URL, or does it need to be accessed through SharePoint web services or some other protocol? I see that people have approached similar problems using WOPI, but I don't think that option is available to me in SharePoint 2010.
Apologies if this is very basic, I'm new to SharePoint and trying to get a complete understanding of what I can and can't do.
