Bonka's Queue is an HTTP-based message queue that relates to JMS or AMQP much in the same way that CouchDB relates to traditional DBMSes. That is to say that it tries to solve a different (much simpler) problem and avoid all the extra overhead associated with more "proper" solutions.
JFileUpload is a Java applet that allows you to upload files and folders to any Web or FTP server. It can be integrated into any application. The server-side technology could be JSP/Servlet, PHP, Coldfusion, CGI, or Microsoft ASP. The front-end provides an upload progress bar, a cancel button, and drag and drop support.
PyAMF provides Action Message Format (AMF) support for Python that is compatible with the Adobe Flash Player. It includes integration with Python Web frameworks like Django, Pylons, Twisted, SQLAlchemy, and more. The Adobe Integrated Runtime and Adobe Flash Player use AMF to communicate between an application and a remote server. AMF encodes remote procedure calls (RPC) into a compact binary representation that can be transferred over HTTP/HTTPS or the RTMP/RTMPS protocol. Objects and data values are serialized into this binary format, which increases performance, allowing applications to load data up to 10 times faster than with text-based formats such as XML or SOAP.
