Hi,
I was watching the following video on File Uploaded in Silverlight for SharEPoint 2010. I have few queries on that:

http://tv.telerik.com/watch/silverlight/video/telerik-silverlight-controls-and-sharepoint-2010-part-5

1. It is mentioned in the video that the ScratchArea folder is not required to chunk the files if we have enabled RBS.
How it differs, where does the chunk data of the large file goes if we are not using / creating the folder.

2. If i have a scenario where i am using the RBS feature of SharePoint 2010 only for files more than 10MB, in such a scenario how can i or where to put the if condition that if the file is less than 10 MB use the ScracthArea folder to chunk the large file . How we can achieve such a scenario?

3. In the video there is a mention about the this.Request.Form["RadUAG_fileName"]. Now if the file is uploaded from 3-4 browsers by different users, how the file names will be?

4. If we are enabling the RBS , whether the uploadhandler.ashx is required.  How different the project (Server Project-SharePoint Empty Project) will be in structure if we are using of have a facility to switch RBS and non-RBS implementation depending upon the size of the file.

5. this video shows the silverlight webpart which is deployed to the SharePoint Page to upload the file. What if i have a silverlight application which is out of SharePoint environment, hosted in some other server. I want to upload a huge file from the silverlight application to the SharePoint Document Library.

Thanks in advance.
