David your point is absolutely correct.  H.261 would be completely unusable.  The max resolution is 352x288 not to mention many other algorithm  issues that make the quality even at low qp's unacceptable especially on a mobile device where the camera is anything but steady

The fact that h.261 is getting so much attention is distressing

well, it’s band-limited and hardly compressed, but within those limits it’s OK.  Whereas I seem to recall having trouble getting decent quality out of H.261 no matter what I did with it (but it has been *years* since I used H.261 for  anything, and it’s only because I am an old geezer that I used it at all).
