I have tried RTM but first it does not work properly (my tasks were deleted) and second I would prefer a self-hosted solution. I also tried to file sync the GTG localfile with Sparkleshare what is not a good solution.
I think GTG would call it a "backend" what I am searching. Is there a way to setup a self-hosted GTG backend or task synchronisation server for GTG clients?
(Please don't suggest Evernote, etc. I am looking for a self-hosted solution.)
