The whole thing - server/client communication, authentication...
managing addons for multiple blender versions, addon dependancies?
support binary files? (so/dll's for eg), dealing with half
installed/corrupt addons on the client, locking so multiple blender
versions don't clobber eachother, getting devs to use tools to manage
it... writing tools to manage it.
All of this can be done - it just takes time & energy, and even once
thats done, I'm not certain it would be adopted by our existing devs.

Yep, we've considered that, its probably most straightforward to begin
with, even so we'd need to have a branch for stable addons so devs
could do improvements without all users getting WIP changes

My impression is addon devs work on their own scripts, and tend not to
maintain other peoples so much.
So when a developer looses interest their addons often stop being

contrib addons are not distributed with blender releases. Im currently
happy with how this works out and dont think we need a more external

you assume right :)
