RE: stds-802-mobility: Hand-off question

Title: Message
Hi,
 
While creating specs for a product many years ago, a wise friend once told me, " seems to me the more you tie it down, the less people will use it."
 
If you spoke to anyone selling wireless bb or to someone building a business out of it, they would tell you they must certainly have a method of session continuity.  Clearly it's desireable.
 
Feature desireability is separate from the challenge of economical design.  We spend mountains of mental energy thinking of every possible excuse to avoid inclusion of a new feature, that is, until we figure out how to do it conveniently. Then, of course it's designed in. We even crow about because now one else has thought of the method.
 
Let's each figure out if we're arguing over practical use (which I would submit is difficult acomplish well in this forum) or if we're instead chaffing because an obvious, inexpensive way to do it has not arrived.......yet.
 
Once we can all see that session continuity is desired, then we can get to the real discussion of how much the method will cost and who will bear it. In my personal view, there will be multi-mode devices in the future. The cost is paid by the user when he chooses a multi-mode or single-mode device/service.
 
Sorry if I sound a little preachy; didn't mean to.
 
Ken

If handoff across air interfaces is not supported, users will need multiple handsets.  Do we really want this situation?

What could be the purpose ?  MBWA is just that - truly broadband, not 3G at all.......

Will handoff be supported between 802.20 and public 3G?
