IPFS backend(s)

[treyzania]

Use a backend such as IPFS to actually store and distribute blocks/etc. to other nodes.

Downsides:

• Relies on external software, which could be automated depending on the situation.
• Not as cool.

Upsides:

• Slightly less targetable.
• Easier.

Something like what might end up happening.

pub enum Address {
    Internal(sig::Hash),
    Ipfs(blob::SmallBlob)
}

I'm not sure how useful internal addresses are going to end up being with this. We might have to separate the notions of block addresses from addresses of artifacts/segments.
