The name sounds like it might approach what I have in mind, indeed.

I tried to relate to an already solved (for my requirements) issue in
the same area, filesync.  
Streaming a video to multiple devices and having handover would mean
- to have a streaming service
- to have both clients involved in the handover receive the stream
- to have 
  - either both clients involved in the handover exchange the handover
    data, i.e. seek positition
  - or have the streaming service care for the position

My idea was to have the content already in both places, i.e. the full
video file.  Then, just the seek position needs to be exchanged, and
after exchange the client is also not depending on a stable network
connection.  Handover for a pdf also fits better into this, as the
files are relatively small.

Thanks for your thoughts!
