Thanks for spending sometime in replying to my query. I haven't really tried by plugin but went through the video on your website as I was really looking to ease the process of using WP with a multi-author team. The video was entirely confusing and I didn't dare to even try it out once... I have been publishing content on 15 WP sites each with multiple authors. Till now I didn't need any special CMS for the same, but one day an Ad Roll AD pointed me to BetaOut so I did a little research on it...
Further regarding to your answer, after running 15 WP sites as I told earlier, for a period of more than 3 years, I never felt the need for Google Docs, Spreadsheets or much administrative work, other than a single sheet for the payment details. I don't know what kind of "Blogs" will really be having Google Docs and Spreadsheets to share with their writers :)
Blogs are open and I don't think much "Administrative" work will help writers. On the contrary, this kind of "Administrative" work kills the creativity of writers, who, I believe, work best when they're up to their own. Binding writers with templates, desks and newsrooms, is a little difficult for me to digest, not to mention a tad difficult to use too!
Anyways, great to see that WP is evolving, may be, only time will tell!!!!!
