Old desire, no new information as far as I know. Found
this thread but it's also ancient history.
This article/thread suggests there may be some export/import options using ical, but that's not what you (or others of us) really mean when we say "sync with Palm."
I thought sure I had seen something "out there" (on SourceForge, maybe?) on someone developing a SDK that might allow for creating such a conduit, but I can't find it now and all I remember was it was way over my head.
I can't speak for internal Zimbrian thought, but I would guess that given Palm has not been exactly front-and-center developing their OS, the impetus to develop a connection to it is not all that strong. I say this sadly since I've been a devoted Palm OS user for close to 11 years. . .MAYBE when/if they come out with that rumored new Palm OS there will be more interest???
You could always file an RFE in Bugzilla and see if anyone votes for it. I would. . .
Cheers,
Dan
