OneDrive Public Folder Question

Question

Hi All,
I have a WinRT C# app that uses the Live SDK v5.6.  In my app a user can upload files and create folders within their OneDrive account and generate share links.  Is there anyway for a user to be able to access files located in another user's specified
public folder on OneDrive? 
Here's what I've got so far: A user creates a folder and sets it to public.  The app creates a 'contact card' file that the user can send to another user.  In this file the sender's ID is stored, along with the web link to their public folder and
that folder's OneDrive ID.  The recipient opens the 'contact card' file in my app and all the values come through successfully.  Now I just need to know how (or if) I can use those values to direct my app to download a list of files in the sender's
public OneDrive folder.  When I try to use the folder ID like so:
LiveOperationResult Aresult = await connectClient.GetAsync(folderID + "/files");
The operation never completes.  I assume this is because the folderID is tied to the sender's user account.  So what are my options here? Is there another value that would work, like upload_location?  Could I use the REST API and the public
web link to get the list of files?  Is there any other way one user can access another user's public folder on OneDrive?  Thanks for your help.

If the file/folder has been shared with the users contact and they are in each others contact list, you can check the files for the pictures and the source returned in the results (something similar to below).  You will also want to make sure that you're
using the wl.contacts_photos scope as well so that you can view the contacts photos.
LiveOperationResultpictureOperationResult
= awaitclient.GetAsync(contact.id
+ "skydrive/files");
dynamicpictureResult = pictureOperationResult.Result;
foreach(dynamicpicture
inpictureResult.data)
varpictureItem =
newSkyDriveItem(picture.id,
picture.name, picture.name, picture.source, picture.description, picture.description, group);
                    group.Items.Add(pictureItem);
