I am thinking of implementing some whiteboarding service for my habahaba
project. However, I don't know which standard should I choose for that:
* XEP-113 is deferred and provides very few functionality;
* XEP-284 can be used for shared editing of SVG document, so it can be
probably used as a whiteboarding service. Am I right? What troubles can
arise if I'll use XEP-284 in such manner? (Also, this XEP is deferred too);
* tkabber has such plugin, but XEP is absence.
