@speednut:

Syncing and a backup strategy are large missing features in Gene's apps... although I have my n810 backed up on my PC, if the device was lost or broken I have no easy way to access the backed-up data until I get a new device and reload everything. Gene's apps are designed to be portable and I believe he runs them on his desktop too, but even at my level of experience with them I probably would need a couple of hours to get them running on my Linux laptop.

A workaround for the backup case would be to export to iCalendar format as part of a (manual) backup procedure. That file could be imported into another calendar app if your NIT went south. Though Gene's todo app can only export to HTML, which is still better than nothing in a backup scenario.

As for erminig syncing Gene's calend, the short answer is no. Read on if you want the details.

I took a peek at erminig's code a few weeks back and it appeared to be reading the GPE sqlite database directly to do its syncing with google's calendar. Also, GPE's sqlite schema seemed to be its own format, and not really using iCalendar. So it would require a fair bit of effort to make erminig work with Gene's calend, and the payoff for that effort would "only" be google syncing.

I haven't delved into opensync too much, but their FAQ lists various plugins for GPE, google calendar, files, and various devices. So far my thinking is that opensync may be a better strategy for syncing, because the payoff for getting Gene's calend and todo to work with opensync is much more than just google.

If there's anybody who wanted to look further into opensync, that would be very helpful for this. Since Gene's calend uses almost-iCalendar format internally, if opensync has a way of syncing with generic iCalendar files then the task is already 80% complete.
