For the network, you're getting 2x 10Gbit connections, configured in an HA-Bond, and plugged into a real switch. There's no current dependency on a virtual networking layer.
Our first iteration, you'll get two networks: "ServiceNet" is our intra-DC network, which is unmetered (ie, free bandwidth) and "PublicNet" which is the internet and will be billed just like we bill for other cloud server bandwidth. Collectively you get 10Gb/s across these, which you can break down however you want. To you these just show up as VLANs which will be configured on build.
We're working on hooking these boxes up to our "Cloud Networks", which are per-tenant software defined networks. If this sounds like a fun project, hit me up, contact info is in my profile.
