Sketch to vector, a Photoshop action

I use the Fujitsu ScanSnap 1100 to scan almost everything I put on paper. I love it! I'm convert my sketches into vector shapes with a simple Photoshop action.

1. Scan something with the ScanSnap 2. Auto-save $datestamp.jpg to folder "/Vectors/originals/" 3. Use Mac OS X folder action on "/Vector/originals/" to open the newly scanned JPG in Photoshop 4. Run the Photoshop action 5. Save $datestamp.psd to folder "/Vectors/" 6. ... 7. Profit?
