Ops, sorry I didnt reply sooner. Some how I overlooked this thread.
We wouldn't be able to have Minion automatically download AddOns from curse but we are working on a feature that would at least allow Minion to detect the AddOn and provide a link to the AddOns info page on curse. Bandwidth is expensive especially when it comes to the scale of the wow community and it would be wrong for Minion to use their bandwidth with nothing in return.
Wowmatrix used to download directly from us and curse and we had to foot the massive bandwidth bills for nothing in return. We don't ever want to do this with Minion.
We also have some projects in the works that should help us attract more authors and make our current authors with us even happier. Can't say much more. So maybe those AddOns will be posted here by the author some day.
