nas - How do I write and submit services (daemons) for WD My Cloud devices?

Question

I like to develop and install a daemon (service) on various NAS systems in order to support an application of mine that runs on desktop computers.

I need help understanding how the various Western Digital "My Cloud" NAS / Home systems work and how I could deploy a daemon on them.

So far, I only have a Synology NAS, where this seems straight-forward: The NAS runs Linux, and all I have to provide is a regular Linux package for it. (I have not done this yet, so correct me if I make wrong assumptions here - I'm still in the planning phase, figuring out what's possible at all.)

But WD systems are confusing to me: While the EX2 systems seems to run a fairly accessible Linux system, similar to Synology's, the "Home" line appears to be more closed. I cannot figure out if it's possible to install any 3rd party extensions on it at all.

So, my questions are:

1. On which kinds of WD devices can I write and install custom services (the service needs to have access to all the shared volumes and be able to respond to inquiries via a TCP socket connection. Ideally, I'd also want to run regular tasks in the background).
2. How would I make the service available to any owner of a WD device, i.e. how do I get my service listed on their "extensions catalog" (Synology offers that, i.e. 1-click installs). Alternatively, can regular users install such services from any 3rd party source?

Any pointers to information on doing this with Synology NAS systems would also be appreciated.
