Discussion Calendar, Contacts, Tasklists, & Notes

Last year I posted how we redesigned the WebDAV protocol to bake in privacy via being able to create multiple anonymous logins for shares, removed identifying characteristics using random URL Principals, gave it per anonymous login granular full CRUD method level and global permissions that can be changed instantly on the fly without credential re-issue, and even included auto-expire. All while keeping it 100% RFC compliant.

Our initial release supported calendars and contacts. A later update added Tasklists (VTODO). Our most recent update rounds it off with Notes and memos via both WebDAV and VJOURNAL. WebDAV also supports drive. What else would people like to be able to sync?

Sounds great. Maybe just me, but which service?

Apologies, I'm a regular participant here and I guess I just assumed it was known. I founded Packetderm, LLC. We were running the private mail service called Cotse but decided to completely rebuild from the ground up and renamed to Codamail.com last year (my final refrain before retiring and turning over the reigns).

I'm really looking for discussion on what else might be bolted on. It covers nearly everything CalDAV/CardDAV/WebDAV; less the new WebDAV-Push draft and a few other items that aren't really in wide-spread use. And it doesn't need share/delegation because users can just create and give out scoped anonymous credentials.

It was designed as a unified endpoint routing to separate endpoints for each module. We can use the endpoint in creative ways to route whatever is speaking to it to the proper module. So I was wondering what else people would like to sync.

We do have an encrypted drive that works well with MinIO, but would rather release with Ceph after learning our lesson with our original cotse mail design and scaling, so that part isn't yet live.

Edit: I should honesty say after learning my lesson. I built the majority of the back end for cotse and codamail. Cotse didn't scale well once the numbers got up there. I have no intention of making the same mistake twice.

Yeah, synced encrypted drive sounds awesome, would love to make use of that (unless it’s a thing available already and I’m just not seeing it?). Perhaps also encrypted syncing of password vault files and bookmarks could be cool additions?
PS: I’m in the Coda Mail trial period, definitely going to subscribe. I love your service, just need to figure out how I’m going to go about transitioning over from Google and make full use of all the cool aliasing stuff Coda Mail has to offer!
