The Cacheability Engine will check a URL you feed it for several things that will affect a Web cache, including web server clock skew, expires and Cache-Control headers, Last-Modified date presence, validation of LM date, Content-Length presence and more. It makes it easy to see how a cache will treat your content. There are also public engines running, so you don't have to install the software to use it for Internet-available sites.

Camserv is an extremely modular program for streaming video from your Linux, FreeBSD, NetBSD, and BSDi machine to Web clients. Filters can be added for text on the displayed window and for anything else one wants to add. It's also very portable because of the modularity of the camera plugin modules, and includes a relay agent which allows the stream to be run more easily on low-bandwidth connections, masqueraded machines, and less-powerful machines. The relay agent can be connected to another relay agent for endless mirroring and paths.
