Just a quick note re: annotation/zoom - the Nokia N810 internet tablet runs xournal (a linux program very similar to our Journal app on the e-ink side -- maybe even the program our app is based on? Didn't we discuss that before?) on an LCD screen and it is capable of zoom/pan annotate functions so you can zoom in, sign, then zoom back out. I've used it extensively for signing documents. So if our app is indeed related to xournal, maybe it's only a matter of time until it works on the edge, too.
