Cell phone home phone interface

  I would like to see a charging cradle for my cell phone that would interface my cell phone with several cordless phones. I could get rid of my land based phone and still have the conveneince of answering and placing calls from cordless phones placed around my house. Even better would be a charging cradle that would accept more than one cell phone and give a distinctive ring so we would know which calls are on my line and which are on another family member's line.
