IPFS compatibility

Use https://github.com/jbenet/js-multihash to generate ids.

Shortening to 128 bits provides 2^64 possible hashes, so should be safe for avoiding collisions:

Use https://github.com/hildjj/node-cbor to compress the files for storage as it will be compatible with IPLD.

Use IPLD syntax for the Parent property:

"Parent": { "@link": "QmAAA...AAA" }

Q: If shortened ids are used, how do you access the full id for the parent property? Can't store it in the json itself as this alters the hash!

A: Redirect to the full id.

Q: Keep using LZW to compress over the wire? Browser CBOR implementation is problematic due to needing to send a byte array instead of a string.

Look at using S3 prefix filtering http://docs.aws.amazon.com/AmazonS3/latest/dev/ListingKeysHierarchy.html
