Kioxia KBG40ZNS256G works as expected in my RBM33 (ext3 with Dude running using it for the data directory).

It seems there is an issue with multicast routing in the the last 2 releases of ROS (on a CCR-1009).

Yes, it is possible, and there is a compileable user space daemon available. But for the "best" solution you have possible other options, depending on your use case. For internal use, in a secure network, you can use other simple tunelling protocols, like IPIP (if you only need IPv4 traffi...

Riccochet did that in the late 1990's and early 2000's somehow successfully.

I assume you refer to 802.3af/at as POE+.

AFAIK all the routing is classless in ROS, since you are free to use whatever netmask you like on any IP. The same goes for the implemented routing protocols except RIP v1.

According to the product description yes, it can. Assuming your TV supports DLNA, of course.
