I recommend trying out Google Cloud Storage; you can access the files from App Engine.
If you want to use the App Engine Blobstore, you can indeed do so from a client. You need to call create_upload_url from within your app, then have the client POST a multipart form to that URL, then have your app handle the response however you wish. One way to do this without writing any new server code which I've used is to use remote_api, set the 'success' url to some handler which doesn't do anything, and handle this entirely on the client. However this means that your server won't have any special knowledge of the files uploaded--you'll have to 'search' for them somehow (the upload size and md5 will match), but that's somethng of a hack. Better to have a tool on your server and client, which understands the entire flow. I suspect there are already tools out there which are public, but I don't know of any off the top of my head.
