The FlashPlus module is set apart from the MemPlug which sticks out the back of the Visor ~2mm and the edge of the CF Card sticks out the top of the MemPlug.  The FlashPlus fits completely flush with the back of a Visor, and the CompactFlash Card sits completely within the Adapter. 

The other exciting possibility is that Kopsis is said to be working on VFS support that will allow the FlashPlus adapter to use almost any application that contains VFS support to access information directly from the CompactFlash card. VFS stands for Virtual File System, and is the system the Palm OS 4.0 uses to read and write to an external memory card. VFS support should work on the Visor Deluxe and Visor Solo running Palm OS 3.1, even though they are running a version of the Palm OS earlier than version 4.0. As long as an application does not use any other OS 4.0 features, FAFileMover will work with it, once the Kopsis VFS add-on software is released.  There have been a number of third-party software programs announce that will support VFS, including BackupBuddyVFS from Blue Nomad.
