I just found the coolest thing at Freewarepalm.com, CF2DOC (or the author's home page, here) !!! It reads text files off the card (using PiVFS on my MemPlug) and converts them to palm DOC files. This is something I've been looking for, to be able to load text files from a PC onto my card and then convert them to use on my Edge. And it's freeware! Since it works w/ PiVFS it should work on any VFS card setup.
