 COMPATIBILITY fixes:
 
 1. COMPATIBILITY: dual-mode devices, i.e. devices exposing both an MTP
   and a USB Mass Storage Device Class (flashdrive) interface are and
   have always been problematic. We must find a way to get this to work,
   eventually. The problem is that the in-kernel mass storage driver hogs
   the device before the MTP mode gets a chance of being used, whereas

   atleast a call to the cache update function.
 
 3. FEATURE: Mechanism to retrieve the device icon device property, else if not
   present, look for DevIcon.fil (Windows ICO format) and
   DevLogo.fil (PNG Format) images from the device (if available).
 
 4. FEATURE: Shared device access so that multiple client applications can have
   an open connection to the device at the same time via a handle. For example,
   it should be somehow possible to run mtp-detect at the same time as amarok or
   mtpfs is connected to a device. This would require some form of resource

-  daemon.
+  sharing.
 
 5. FEATURE: Implement an OpenSync backend for devices which have
   calendaring, contact etc support. http://opensync.org/
 
 
 THOSE ARE ALREADY DONE:
 
 1. FEATURE: Make an API that can return several devices and let the user
   choose which one to operate, not just connect to the first one...

 9. SPEEDUP: The recursive function that builds the folder tree is
   O(n^2)! Atleast remove all non-folders (PTP associations) from the
   list before we start sorting and building that tree. We walk the
   entire list for each group of siblings right now!
 
 10. FEATURE: program to autoprobe device interfaces on connection.
 
 11. FEATURE: accomodate Googles uncached device needs.
 
 12. FEATURE: rudimentary event interface.
