That said, to prevent scaring programmers: I should stress that minimal implementation of XEP-0301 (following ONLY the 'REQUIRED'), is actually really simple. In my experience, it added only 500 lines of code to an existing instant messaging program. Very easy XEP-0301 is basically supporting ONLY the Tier 1 elements, XML action elements: insert text, backspace, and forward delete. (Note: They can be used for en-bloc operations, including cut, copy and paste behavior). If nobody on XMPP objects, I'm going to mention that 300ms interval is recommended, when following minimal XEP-0301 implementation, to avoid uncomfortable bursty output. As a simplicity test of XEP-0301, somebody (one of us) should add XEP-0301 support to Pidgin or Miranda, or one of the other open source XMPP clients, seeing how quickly we might be able to add the baseline feature in the first pass of programming. (and more complete XEP-0301 in a second pass of programming) Cheers Mark Rejhon
