Installing the plugin was incredibly simple, so, thats a good start :) 

A couple of things I've found so far are:

1: Rendering out via the plugin takes a lot longer than if you were going to render a png sequence without the plugin - the sequence took nearly an hour?

2: When rendering out via the plugin, I've noticed a couple of gremlins with the render, one of the characters slides around, and the eyes go a bit strange.

3: Also, for some reason, when rendering out via the plugin, the characters import into AE slightly squashed - I can fix this manually, no problem - however, its a little strange - I can look into my AE settings to see if anything is wrong with the way AE is set up?

I've rendered out a little sequence - its not a final sequence (and I need to fix the directions of the eyes, this was really just a quick render to see how it talks to After Effects, so, don't worry, I will do MUCH better tests and renders, this is just something to get the ball rolling.

Overall though, apart from the few little things I've noticed on this quick test, I think its great, I love the way each character renders out as a separate image sequence, that will really help when working in After Effects as you can reposition the characters if needed.

I will do more tests in the morning :)
