简单的说，我觉得有用的就是
$"QåúÖ www.flash-bbs.comÁí}D[¡[|1.提高了性能
$"QåúÖ www.flash-bbs.comÁí}D[¡[|2.支持H.264 和 AAC流
$"QåúÖ www.flash-bbs.comÁí}D[¡[|3.新的安全协议
$"QåúÖ www.flash-bbs.comÁí}D[¡[|4.数字版权保护
$"QåúÖ www.flash-bbs.comÁí}D[¡[|5.可以广播到手机等移动设备
$"QåúÖ www.flash-bbs.comÁí}D[¡[|其他的感觉现在用处不大
$"QåúÖ www.flash-bbs.comÁí}D[¡[|$"QåúÖ www.flash-bbs.comÁí}D[¡[|不幸的是，服务器端还必须用AS1.0，
$"QåúÖ www.flash-bbs.comÁí}D[¡[|不过支持AMF3后，可以传递图像对象了，
$"QåúÖ www.flash-bbs.comÁí}D[¡[|也就是说以前说的聊天工具中发自定义表情可以实现了，
$"QåúÖ www.flash-bbs.comÁí}D[¡[|不知道可不可以更进一步，传递文件对象，实现点对点传递文件，这个要发布之后才能测试了
$"QåúÖ www.flash-bbs.comÁí}D[¡[|添加了服务器端的播放列表功能，也就是说可以制作自己的网络电视台了，哈哈，不用再用什么垃圾收费的虚拟摄像头了
$"QåúÖ www.flash-bbs.comÁí}D[¡[|负载均衡方面好像也有所进步
$"QåúÖ www.flash-bbs.comÁí}D[¡[|$"QåúÖ www.flash-bbs.comÁí}D[¡[|让我们一起期待FMS3吧

$"QåúÖ www.flash-bbs.comÁí}D[¡[|$"QåúÖ www.flash-bbs.comÁí}D[¡[|1)Improved performance — Adobe Flash Media Server 3 software will increase its capacity for the number of concurrent streams by over 200% compared with the previous version. This improvement will help lower the cost per stream, because more streams can be delivered per server. The performance gains will be achieved in both Windows® and Linux® Red Hat® 4 implementations. Adobe will publicly release performance benchmarks when the product ships.
$"QåúÖ www.flash-bbs.comÁí}D[¡[|2)H.264 and AAC streaming support — Adobe Flash Media Server 3 will support streaming of industry-standard H.264 and HE-AAC video and audio content to Flash Player, Adobe AIR™, and Adobe Media Player. Flash Media Server 3 will also support enhanced seeking for H.264 content, which means you can seek to any point within the video and start streaming quickly.
$"QåúÖ www.flash-bbs.comÁí}D[¡[|3)New security features — Adobe's Real Time Messaging Protocol (RTMP) will be enhanced with new, higher performance encryption to help secure streamed media and communication. This enhanced protocol is called RTMPE. Similar in strength to our current SSL protocol (RTMPS), this enhancement can be leveraged by content owners and communication developers to add additional protection to their content. Additionally, SWF verification will also help protect SWF files from being reused, modified, or hosted in alternate locations. Flash Media Server 3 will also support streaming of encrypted content to Adobe Media Player.
$"QåúÖ www.flash-bbs.comÁí}D[¡[|4)Improved live video support — Adobe Flash Media Server 3 will introduce scalable live streaming support for high-quality video and audio streams from Adobe Flash Media Encoder. This will allow more live streams to be hosted from a single Flash Media Server.
$"QåúÖ www.flash-bbs.comÁí}D[¡[|Adobe Media Player support — Adobe Flash Media Server 3 will introduce content measurement services for the upcoming release of Adobe Media Player. Flash Media Server 3 can also be used to stream protected content to Adobe Media Player.
$"QåúÖ www.flash-bbs.comÁí}D[¡[|5)Mobile video delivery to Flash Lite™ 3 — Adobe Flash Media Server will support both prerecorded and live streaming to the Flash Lite 3 mobile platform. The same video experience in the browser can now be delivered to mobile devices supporting Flash Lite 3.
$"QåúÖ www.flash-bbs.comÁí}D[¡[|6)Better out-of-the-box experience — Adobe Flash Media Server 3 will ship with special prebuilt services to make it easier to stream. The documentation and help systems have also been completely updated to support ActionScript™ 3 in Adobe Flex™ and Flash CS3 Professional.
$"QåúÖ www.flash-bbs.comÁí}D[¡[|7)New plug-in architecture — Adobe Flash Media Server 3 will increase its extensibility by introducing powerful new C++ APIs to customize the built-in authentication and file access functionality. These plug-ins can be used to develop geo-filtered content or HTTP-based Origin services.
$"QåúÖ www.flash-bbs.comÁí}D[¡[|8)Server-side republish — This exciting new feature will let developers push either a live stream or a playlist to another Flash Media Server or content delivery network (CDN). A developer can inject cue-point messages into a live stream before it gets distributed, making it easier to develop applications that react to the video events.
