Just buy the plugin and get on the beta. That way you can use this plugin now with 2010. I bought it and got on the beta and am very impressed with the workflow of Boomer Labs plugin. I've got a project I'm working on right now with where the client likes to make multiple revisions and the plugin is saving me tons of time. You will need to buy the product and then sign up for the beta here. Here is a copy of Matt's old posts.
Beta is now open for existing license owners. To gain access to the Beta, please fill out the following:
http://www.boomerlabs.com/beta/nda2.php
Just put "none" in for username and password as we will not have a discussion forum for this beta. Project name is "MAX2AE 2010".
I should mention that you still need to submit your proper email address.
Also, please put your existing serial number in the comments section.
