sheerdns is a master DNS server whose zone RECORDs are stored on a One-RECORD-Per-File bases. Because of this, it is the simplest of any DNS to configure, the easiest to update, and the most efficient for networks that experience a lot of updates (for example master servers for dynamic IP address ranges). You never have to restart it; any updates are available immediately without having to notify the sheerdns process. 來源: http://freshmeat.net/projects/sheerdns/?topic_id=149 sheerdns是一個主DNS服務器，它的域記錄保存在一個One-RECORD-Per-File（每文件一個記錄）的庫中。因此，它是最簡單的DNS配制，最容易更新，對于有大量更新的網絡（如動態IP地址范圍的主服務器）來說它是最高效的。你不必重新啟動它，任何更新不用通知對應DNS進程就可以立即生效。
SDP Search and RECORD generator
OVERVIEW:
Recognizing the difficulty in creating an SDP service description and search
from scratch, Microsoft is providing a sample utility in bthnscreate.cxx to
automatically create a service or RECORD. This utility can be run to create
an SDP RECORD or to setup an SDP Service, Attribute, or ServiceAttribute
search based on information stored in a human readable file.
FFmpeg is a complete solution to RECORD, convert and stream audio and video. It includes libavcodec, the leading audio/video codec library. FFmpeg is developed under Linux, but it can compiled under most operating systems, including Windows.
