Does this auto-discovery, or how to i link different local calendars to multiple remote calendars?

There's CalDAV-Sync for Android which does exactly that: you provide the sync URL, and it fetches info about available calendars. Then you can choose which one to sync, and those get automatically created locally too. Perfect! I really love it on my tablet.

After all, syncevolution is such a hassle to configure, i never got it to work failure-free using SyncMLwith my 8-10 memotoo.com calendars (different error codes, also only "Download from server" (full data replacement) worked to some degree). Multiple calendars, because N900 doesn't support categories.
