ACE: Collaborative text editing
ACE is a platform-independent, collaborative text editor.
ACE allows multiple geographically dispersed users to view and edit a shared text document at the same time, thus facilitating efficient teamwork.
According to available knowledge, there is only one such application; it works well and has reached widespread use. Unfortunately, it is limited to the Mac platform.
ACE is the first collaborative text editor that runs across all major platforms, including Windows, Linux, and Mac.
ACE builds upon open technologies such as BEEP (RFC 3080) and zero-conf networking; all this leaves the possibility open to communicate even with different applications that understand the public protocol of ACE.
