I would like radCloudUploader to be able to integrate with DropBox (and skydrive?) 
As my client has a large investment in DropBox (cos it works on mobile), but I want to be able to upload documents to a given project (subdirectory) via a single interface without giving them total access to that directory.

I would also like to have some integration to a search service such as Azure Search
https://msdn.microsoft.com/en-gb/library/azure/dn798927.aspx 
so that documents uploaded can be searched.

Which results in me adding lots of 'meta data' to the file that is being uploaded, but the actual content can have a free text search on there.
