Maybe some reading software does it, but it would have to use some server.
That means that you'd have to leave WiFi on.
Ok, you could come up with a solution which synchronized over a USB connection.
Still, that's also a bit cumbersome.
Then there is the question of what kind of data is used for position. It's all different between different reader software. If you stick to one software you're ok treating reading position as an opaque blob.
For instance, on my current book I'm on page 75, that is "chapter6.xhtml#point(/1/4/2/28/3:208)".
The numbers represent HTML nodes.
