To clarify - the full client will be very minimal.
i.e. no facility for editing your profile, joining pubs, etc

It might be a very minmal fork of patchbay. The good news it the patchcore and-scuttle-helper work make building apps really quick (especially given I know the neighbourhood)

Good question about documenting. I'd make simple readmes. I honestly think the scuttle-pattern is designed to be easy to consume. This still needs testing.

The amount to deliver might indeed be ambitious. Estimating a months work is quite challenging. This is something I would want to work on in my spare time if possible, but being offered money to help would mean I wouldn't need to be doing other work while trying to do it and could build much quicker and higher quality.

Thanks for the thoughts / questions @elavoie. They've drawn my attention to things that will make my planning stronger
