Being not an Android programmer, I looked around for generic code which could make it in such a replacement. So far I found these:

- The flicker-free page turn code used in cool reader:

- Max Kammerer's code for his nook port of aarddict:

Code:
// from kbs - trook.projectsource code.

private final void pageUp() {
        int cury = articleView2.getScrollY();
        if (cury == 0) { return; }
        int newy = cury - WEB_SCROLL_PX;
        if (newy < 0) {
            newy = 0;
        }
        articleView2.scrollTo(0, newy);

}

private final void pageDown() {

        int cury = articleView2.getScrollY();
        int hmax = articleView2.getContentHeight() - 200;
        if (hmax < 0) {
            hmax = 0;
        }
        int newy = cury + WEB_SCROLL_PX;
        if (newy > hmax) {
            newy = hmax;
        }
        if (cury != newy) {
            articleView2.scrollTo(0, newy);
        }

}
Cool reader has very low page turn flicker, the second code I could not see in action.

In an e-ink friendly app, there would be an option to select high-contrast skins and optimize page refreshes.

Once the keyword "e-ink" or "e-ink friendly" will show up in the Android Market, then we've got the ball rolling.
