I’m not sure if I phrased this question correctly…
My wife and I have one blog, family.com in this example, that we both contribute to.
I would like family.com to show all blog posts.
me.family.com would show only posts I author and her.family.com would show only posts she authors. later, we will add kid1.family.com and so on…
further, sometimes she/I/we do projects that grow beyond one post. project1.com would show only all posts in the ‘project1’ category. However, unlike authors, only specific categories would have their own domain names.
wp-subdomains-revisited plus domain-mapping-system used together seem closest to what I am looking for but they’re outdated and I’m sure I couldn’t replicate them myself.
Edit 1: I found this wonderful answer by mikeschinkel: Multiple Domain Names – One WP Install (non-Multisite) – Default Each Domain name to Category Archive
Edit 2: I got mikeschinkel’s code working on my site. Great! Now, I’ve been trying to modify it to work with subdomains as well. That has not gone so well – only a white page loads when my modifications are in place.
Edit 3: The site is loading again with working domains and subdomains! How exciting!
Next task is to have all links use their respective domain/subdomain. For example, a post holiday written by me and in category project1 should appear as family.com/holiday, me.family.com/holiday or project1.com/holiday depending on which sub/domain it’s linked from. Any suggestions would be wildly appreciated!!!
(also, it will have to work with WPML -> me.family.com/holiday, when translated, should become her.family.com/休日/ … frightening!)
Edit 4: Just to clarify, functionally this should be no different than viewing an individual author or category archive, the only difference being the archive will have it’s own sub/domain.
Also, my TLD is .is… and my domain is my family name. That means my URL is halfway to being a sentence -> _adam.rabbit.is/…
The goal is to have a url specific to whatever relationship:
adam.rabbit.is/gardening
wife.rabbit.is/coding
rabbit.is/travelling
Edit 5: Updated code – mostly working now. I’m reluctant to mark it as solved because I haven’t removed the base category or added separate header/title for each page… but as is this code works and solves the main question of the post. I hope someone else finds it useful 🙂
Edit 6: I found a nice plugin called wp-no-base-permalink which removes the category base. I updated the code to work with this plugin. Now if I type adam.rabbit.is/uncategorized it shows all uncategorized posts by me – exactly what I was looking for!

And, of course, you also need to point your subdomains (or *) on your nameserver to your wordpress install. You also will need to add a Virtual Host (Nginx) for any other domains you are using… and you will need to set up CORS.
As a side note, this answer used in conjuction with my next answer/question – How to have a static category/author page? – should make my intentions of having one multi-faced site a little more clear 🙂
