Trading a collection of assets for a single payment

Bounty idea

Let's discuss if we can define a bounty that evolves around the idea of selling collections of assets (call them badges (noooo), NFTs or just collection).

Mechanism to offer collection of assets as a whole for sale

Given the case someone has gathered a nice collection of assets and wants to sell them all-or-none (you wouldn't do that with your precious quest-badges, would ya?), this can currently be done in an atomic transaction under the following circumstances:

• Both parties agree to (multi-)sign the transaction
• There are not more then 99 assets included in the collection-to-be-sold (one operation needs to cover the counter-payment)
• The assets are offered as claimable balances (otherwise the amount of possible assets would half due to necessity to establish trustlines - or even get split three ways when removing seller's trustlines in the same TX)
• After the deal has sealed the seller needs to remove all trustlines manually – a presigned 'remove the trustlines' transaction could be added to the seller's account to make this more easy

Placing an offer that can be taken by an arbitrary counterpart

It is desireable that someone does not have to advertise their collection manually and than agree on a multi-sig scenario where XDRs need to be transferred between both parties to settle the deal with the (probably not so tech-savvvy) potential buyer.

👀 Love this idea. Let me give it some thought and get back to you. This is the type of bounty I'm here for. Highly educational but also quite practical. ❤️

Thank you. I already see some different ways this could be approached but I first wanted to get the discussion started.

Would be cool to explore this in the Turrets ecosystem, though not required, they will need some good examples of more real world use cases and this may be a great one.
