    We intend to develop a wifi enabled p2p file sharing system on a linux platform using jxta and java. The purpose is to build a system that can be ported to an embedded device at a later stage and be used for p2p file sharing using the 802.11b standard. 我们旨在Linux平台上使用jxta 和java来开发一个支持wifi的p2p文件共享系统。其目的是建造一个以后可以移植到嵌入式设备的系统,使用802.11b标准进行p2p文件共享。 来源: http://sourceforge.net/projects/linux-p2p-wifi/-We intend to develop a wifi enabled peer-to-peer file sharing system on a Linux platform using JXTA and java.
