Parsing through your comment, are you suggesting that be better clarify
some instances, such as
1) Closed 'phone' with no additional external interfaces,
limited software & upgradability.
2) PDA / phone, small device, small configuration ability,
some ability to run extra applications, additional
interfaces possible.
3) PCMCIA radio card on a full-powered laptop, with
a commercial IP stack
If this is useful, then we could then clarify in more detail the
difference between a 'host' and a 'router' - I do think that if
we try to cover both cases in a single draft, we will run into
trouble.
Again, the authors do see that some devices will have personal
area networks and may route packets, but we feel that this would
be best to specify in another document, because there are a lot
of different issues involved and this model (phone as personal
router) has less applicability than a more generic 'phone'
as an endpoint.
