We would need more details/resources in this document.

1. I can't find proper specification of Session Keys in Ethereum ERCs, can you link the resources you based your research on?
2. Can you define technically how a session key would look like?
3. What would be the scopes?
4. Ideally we include in this document very precise specifications of our session keys.

1. There are plenty of theoretical resources regarding session keys and I found this interesting example of contracts with session keys management there https://github.com/itublockchain/eth-paris-session-key/tree/master/account-contracts/contracts (and the app is also interesting for us)
2. It's private-public eth key pair
3. Normally in scopes you can define methods that your session key can use but it also can be extended with spending limits for example
4. For precise documents we will need a few people I guess
