Gossamer Community is quite far from simple (I assume). It has to tie all scripts together and as we are all aware of the Alex's ability then I don't think it would have taken this long unless it was a large task.
The people obtaining copies in what you call a strange way, are only actually beta testing the script, which is an important part of the development process before the script is released to a wider audience. The beta testers can then help to weed out any obvious bugs.
The last thing I heard, which was a week or two ago was that the community plugin will be released soon after christmas. I don't want to give out false information so don't take my post as gospel but I *think* it is quite accurate.
