Open RSS Bar is a Flash-based RSS reader. You can create example URLs to any feed in the library by clicking the OpenRSSBar in the Feed Library Reader. To link to feeds outside the feed library or a compliant service, you need to modify the Flash source a bit. You can use it indirectly by linking an iframe to the http://www.feedlibrary.org/openrssbar/openrssbar.html page or by adding the Flash directly to your site and providing a WebService proxy to the Feed Library WebService.
MultiLoad is a load balancer that redirects HTTP requests to pre-defined servers/locations. It gives the provider a way to balance the traffic and hides the real download location. It allows you to manage different version of each download. It is also a load balancing server extension. You can distribute files on some servers so that a downloaded file can be loaded form different servers. These servers can have different priorities to control the active traffic.
