When you are using Dante-enabled equipment you normally also wanna integrate computers into this network. There are two ways to do this. You can either use a software driver called "Dante Virtual Soundcard", provided by Audinate (Australian inventor of Dante; 30,- $), which turns the computer's standard integrated RJ45 NIC/LAN port into a 64 channel i/o audio interface or you can purchase dedicated Dante PCIe form factor cards which provide Dante connectivity. Such a card needs to either be installed into a computer's free PCIe slot (in case of Windows) or into a PCIe-to-TB expansion box available for Mac computers.
Main difference between using the Dante Virtual Soundcard driver and a Dante hardware PCIe card is the higher channel count of the latter (up to 128 channels i/o) and also its significantly lower latency. While DVS has typical latencies of 5~20 ms, Dante hardware devices (and thus a Dante PCIe card also) have typical latencies of 1~5 ms or even less (depending on the specs of the computer). So, if your environment requires very low latencies (for example playing VST instruments live while monitoring them directly) you'd need to use a dedicated Dante PCIe card because you'd get too much latency using DVS. Other real-time audio tasks also require very low latency (like in live scenarios).
If you do not require real-time audio processing or monitoring, you could very well use DVS. Also, if the computer running DVS only has to play back prerecorded audio or is used to simply record without using direct monitoring, DVS is absolutely appropriate, providing the considerable amount of 64 audio i/o's.
This is the Dante PCIe card I'm using:

Yamaha. The system requirements for Mac are shown in the list. Retail prices are around 1.000,- $. Similar/identical cards are currently available from SSL and Focusrite (RedNet PCIe).
Mounted into my Intel i5 Windows computer (not the most powerful machine on earth) I can set the latency low enough to be able to play VST instruments live incl. a no. of VST fx plugins on top of the intrument. Apart from that, it allows me to route up to 128 audio channels to and from my daw. Those channels originate mainly from my ad/da-converter and a Dante-enabled digital mixing console while the daw's output channels are in turn routed to my SSL Sigma summing engine for mixing and to my analog outboard. As shown in the video, Dante-anabled devices auto-discover themselves within seconds after they have been connected to the network or powerded on and you can route arbitrary channels between any of the devices with a single mouse click.
For live recording tasks, I'm using an Intel i7 laptop (Windows) running Dante Virtual Soundcard which is directly connected to a Focusrite RedNet 4 (8-channel mic/line preamp) and a Dante-enabled Yamaha 01v96 to record up to 24 audio channels via a single cat 6 cable. I'm using a small manageable Cisco 8-port gigabit switch to connect all three devices.
What is your environment like and what requirements do you have? This determins if Dante is suitable for you.
