i have installed your plugin without any trouble and it seems to work nice so far. As you've mentioned, some things don't work yet. In my case i am running a german blog and an english blog in a network. It seems that only the comments in the main blog are displayed correctly on the joined pages, but unfortunately not the other way around.
Can You please tell me how long it will take, until a release of your plugin for production use? It seems, that this plugin is in my case the only solution to synchronize comments between my blogs, so i need it urgent.
