How to Do a Sparrow Multi-Seag and You've Got Keys in Different Locations?

Sparrow multi-seag wallets can be used to sign and send money. The most key thing is that apart from backups of the seeds of all the individual devices or at least a quorum of them you need to have an output descriptor which Sparrow now presents to the user when they first create their wallet. You then recreate the spending script whenever you want to spend and that contains the public keys to that address. Then if you need to restore your wallet you can basically just plug that in and your entire wallet will then pop up  and so long as you still have aquorum of the devices you'll be able tosign and send right.
