A few notes about Palm and Linux : I am still searching a way to convert .jpg to .pdb, so I can send images to the Palm Zire.
(From the “External Links” of pilot-link.org/)
KPilot : quite good.
JPilot : to test again. (It didn’t sync.)
ColdSync : command line.
http://pilotmanager.sourceforge.net/ Looks old ?
http://www.pyrite.org/ Text and Database conversion : no sync.
pilot-mailsync transfer mails to a Palm using the Palm Mail application. It relies on the libraries installed by pilot-link.
Some more programs from TuxMobil (many links broken) :
PalmImage looks like it stoped in 2000. Only support grayscale (4bits).
