Whoops! I spoke too soon. Here is what it further says: "A FUSE-based full-featured implementation is currently in beta status. A proprietary, read/write solution, licensed and derived from the Microsoft exFAT implementation, is available for Android, Linux and other operating systems from Tuxera. A proprietary, full-featured implementation—XCFiles—is available from Datalight. A full-featured implementation for embedded devices —Rtfs—is available from EBS Embedded software."
Nothing says it will be free, tho. --doug
