Looks like never to me. This thread is now 6 months old. Losing interest by the week.
Sorry guys, I was forced to stop the work on this plugin for some long time right after this annonce was made, as I was in process of moving to NZ for a couple of months... Changing the country to other side of the earth by all the family is a very nervious and time consuming process, so I was not able to work all this time... At the time of this annonce the plugin was only about 1 week old but was already in some working state.
But the last two months I work on this plugin with the full force, so I think you will see the beta in not very long time, as it is almost ready for alpha now.
