Working on a driver for this. Watch this space. :) (been trying to go fulltime on this, financial constraints have been holding me back; I have a partial prototype working on Linux, Mac OS X is the next target)
That said, there are existing solutions for this, they just suck, e.g.:
http://www.seagate.com/www/en-us/products/laptops/laptop-hdd http://www.seagate.com/www/en-us/products/laptops/laptop-hdd (only 4GB Flash, WTF?)

http://en.wikipedia.org/wiki/ReadyBoost http://en.wikipedia.org/wiki/ReadyBoost (designed to work with USB sticks of all things, and isn't terribly smart about what to cache)
- stcredzero 16y agoWhat about a daemon that migrates files over and symlinks them?
- pmjordan 16y agoBrittle. Many apps will delete and replace a file when writing. Now you have 2 copies, 1 out of date. You'd be mildly better off with a union file system, but there aren't any good ones I can find. Plus, that sort of file-based system doesn't cache file system structure/metadata, which is a major source of disk head movement.
