Appliques Machine

What programs exist to convert artwork to Embroidery Designs?
I do embroidery and applique and quilt piecing hand, usually of my own drawings. I am interested in the automation of these processes as much as possible, because I am losing both manual dexterity and vision age. From my investigations so far, Embroidery Machine manufacturers offer proprietary software with their machines, limiting the design of the machine. In addition, Each design is a cost. One can buy a software to convert designs into other formats, but the conversions often lose something in translation. What I want is power use my own design, one of my graphics programs, and duplicate it in a cloth and threads. Any advice for those of you who write software, or are fiber artists?
