Explore design space for `session` intent

[lgalabru]

The first approach available in this repo for the session intent is being approached through a swig smart account.

The design space is large. We can and should support more smart accounts solutions (Squads, LazorKit, etc), but also could explore tailored solutions like payment channels, etc.

Hey @lgalabru,

this repo is awesome. I have been waiting for a good protocol to implement subscriptions for a while - x402 still behind and EVM focused. Glad to see another, more general approach on MPP.

Either way, i wanted to get in touch and see if we can work something out avoids the smart accounts. From a user's point of view, smart wallets are separate from their main balances and still hard to handle (I haven't seen them integrated into wallets yet, have they).

The project i am working on (tributary.so) goes a different way and hooks into token delegation. You essentially authorize a smart contract to spend from your wallets directly. That way users can have their invoices paid automatically when they are due and directly from their wallet.

It does support pay-as-you-go as a payment policy as well. So I was wondering what it would take to get Tributary integrated as a payment channel.
