Setting up Backroll with Epic Online Services

[jososide]

Having a version of Backroll setup with EOS that would allow for Rollback Netcode with crossplay on Unity games would be the next step in making Rollback a more mainstream friendly option in regards to deterministic game development

Ultimately this is reliant on the following:

• Seeing if Epic has support for purely P2P connections in Epic Online Services,
• Are these features accessible in the current C# SDK?
• How difficult it would be to implement this into HouraiNetworking.
• Are there any legally binding terms if linking against the SDK?

These are also non-blockers but something worthwhile to bring up:

• Packaging: Is Epic's SDK usage OK with us redistributing it via a Unity Package Manager repository?

Seeing if Epic has support for purely P2P connections in Epic Online Services, -They have a nat p2p interface.

Are these features accessible in the current C# SDK? -Yes

How difficult it would be to implement this into HouraiNetworking. -It doesn't look particularly different then most network libraries.

Are there any legally binding terms if linking against the SDK? -The EOS is a plugin and you aren't linking against it.

Packaging: Is Epic's SDK usage OK with us redistributing it via a Unity Package Manager repository? -No you can't the SDK requires client credentials to authorize.

At this rate, please use UnityGGPO, I'm more focused on maintaining the Rust version of this library than the Unity C# one.
