Digital Caliper as a Digital Readout on Small Mill

[sanddrag]

Is there a way to use a digital caliper as a digital readout on a small mill. See, Harbor Freight tools sells this little Micro Mill for under $300 but it is, in traditional Harbor Freight quality, very inaccurate. If you could add some digital calipers to the slides and use it as a digital readout,this little mill's potential would be greatly increased. So, is this possible?
