"TrueOS Pico™ is currently in beta status. The client has experimental support for VirtualGL, and limited sound-forwarding availability. Additionally, there is a limit of 5 concurrent sessions on the server side. Licensing options will be announced at a later date."
I was interested in the thin client concept few years ago and tried virtualgl. It is really nice and impressive. There are few different configurations available. I aimed for low latency and 30 fps gaming was easy to achieve over 1gb link (it needs wide bandwith as expected).
Our company has been running LSTP on commodity hardware since 2013 for a development team, and I am truly happy with the result.
For a long time, a 2013 i7 CPU with 32 GiB RAM running LTSP over ESXi was more than enough for intensive use of 5 thin clients.
We've recently switched to a more powerful server (refurbished 48 AMD cores / 256 GB RAM) running Proxmox and despite some issues that still needs minor tweaking, I am very happy with it.
The only gray area, and the reason I am always looking for alternatives to LTSP (NX2Go is the strongest candidate), is the huge bandwidth used by LTSP: 8 Thin clients needs a sustained 600 Mbps. I'm afraid scaling over 10 / 15 workstations will require expensive network equipment but graphic user experience is near native in all aspects.
I highly recommend to anyone that is in doubt of using LTSP or any other thin client setup in production, give it a try because it actually worth it in all aspects.
I remember using XDMCP ~20 years ago for this (underpowered machine as thin-client to beefy server, with graphical login). Does LTSP have additional features or better performance?
I would be nice if there was a video demonstrating the thin client capabilities of this. I for one would like to see the OpenGL in action (yes, show me games!).
Plus, which Pi is this made for? I am assuming the Raspberry Pi 2 & 3 (ARMv7). I have all 3 model B's so I'll check this out.

The Linux equivalent would be something like LTSP (http://www.ltsp.org/)
rPI's aren't too far off sunrays which worked very well, but I think ALP is prop?
I've not had a play with Spice, shurely this isn't just X forwarding over SSH?

Hopefully, that won't be the case soon! [0] I've no idea how far away the tech is for production use, but I'm quite excited by it myself.

Alternative was to use a 4 ports NIC with bonding but 10Gb will be far more easy and stable.
LTSP Clients boot with PXE and get the root filesystem via NFS, then it uses XDMCP login screen.
AFAIK, LTSP 5 uses LDM instead of XDCMP.
