It looks like the latest release of MakeMKV has added live playback of Blu-ray discs:

Edit: Here's how it's done:
Insert a Blu-ray disc, then after it mounts in the Finder launch Make MKV 1.4.10 beta. After it reads the disc, click on the Open Disc icon and it starts decrypting the disc. This takes about 30 seconds to complete. You're then presented with a list of titles - find the largest as that's likely the movie. Next click on the Make MKV server icon to launch the server, then click on the http link in the server box. This opens a window in your web browser with something like this:
This page is designed to be read by robots, not humans. For this it is a valid xhtml text document with a simple structure. Each page contains exactly one table that in turn contains name-value pairs which may point to other tables (web pages) or files to stream.
This feature is experimental - discs that use seamless branching will likely not work.

address 10.0.0.2:51000
titles /web/titles
Click on '/web/titles' to get to the next window:

name Star Trek Disc 1
titlecount 5
title0 /web/title0
title1 /web/title1
title2 /web/title2
title3 /web/title3
title4 /web/title4
In the case of Star Trek, title2 is the main feature. I click on the title2 link and then get this in a new Firefox tab:
name value
id 2
duration 2:06:50
chaptercount 14
formatcount 2
format0 m2ts
file0 /stream/title2.m2ts
format1 ts
file1 /stream/title2.ts
Click on the link /stream/title2.m2ts and a new tab opens in Firefox with the Quicktime icon. Copy the URL and then open VLC, choose File > Open Network and paste the URL into the box, hit return and the movie starts playing.
I think there might be a plugin for Plex in the next day or two that will simplify this. Keep your fingers crossed.
