Yeah, they're kind of -- there's two different purposes. One of them, which is the Forte enterprise and tempo systems. Those ones are people are worried about uptime and they're looking for as high an AQ number as they can possibly get. And so, they're building applications with those things. The networking is more on the R&D side, and so, what they're looking to do is to get quantum computers and then add in their own hardware to be able to do quantum networking. And so sometimes they're asking for us to make modifications so it's compatible with their hardware. It is -- they don't care about so much about the number of qubits or the AQ. That's not really their focus. And they're more workbench systems. They care more about can we share technical information so that they can figure out how to integrate their hardware in. So, it's kind of two different, and as far as uptime concerned, I mean, that's not really the goal of networking systems in the short term. It's not really about total uptime. It's more like, well, can we get the basics to work or can we get it to work over maybe starting at a mile and then over 10 miles and a hundred miles and hopefully eventually thousands of miles. So, it's much more of a R&D phase than what you see in the other systems, which are really production systems. Obviously, sometime in the future we hope that quantum networking is a thing and it will drive tremendous demand for production systems. Because if you're going to build a quantum internet, you're going to need a lot of these things. And but that's obvious. We're not selling that yet today. It's mostly in R&D. I don't know if Dean, you would have, so to give you a little bit of color in terms of just the differences between the hardware and the machines, the software stacks can change based off of the customer needs, for example. And so, some of the research customer software stack, we need to tailor to AFRL's needs. On the hardware side the hardware is a lower qubit system to be able to support the networking. Similar atomic species, they're both barium systems. It's like our tempo systems and the systems for AFRL, the optical system design has a lot of leverage from our existing systems. A lot of the mechanical design has carryover. There's some of the readout and everything is different based off of the needs of our networking. And so, while there are many common components, there are some distinct pieces, networking being one piece of it, but just part of it is just the needs of the research community versus the needs of a commercial installation.
