I spent a little more time working on BlobFu. Now, it supports stream and byte-array publication and generic support for uploading and downloading in-memory objects to and from Azure blob storage. Within minutes you could be uploading anything - files or serializable object instances - to your Azure blob storage account. Via NuGet, BlobFu is available for anyone's use.
To get it, just use Visual Studio or WebMatrix 2 (which also supports NuGet packages) and install the package into your project and start using the BlobFuService class to upload and download files to Azure blob storage.
Happy blob storage!
