Hi Don,

If Bluetooth supports IP (network layer) at all, then it 
inherently supports both UDP and TCP and all applications
(although operational parameters of both UDP and TCP would
probably be tuned differently than over Ethernet or ATM).

Cheers,

My understanding is that standard blue-tooth only supports UPD and not TCP.

Regarding bluetooth - my assumption was that there would be IP over BT. Then
we
can do plain old IPP rather than inventing something new - or am I missing
something here.

Regarding IR - the good thing about it is that ~100% of laptops and many
PDAs
have it today - and yet it is poorly exploited anywhere. Secondly it is an
inherently point and shoot interface which make it ideal for things like
printing where you are communicating with a specific piece of hardware as
opposed to a virtualized service. I know there is IP over IR but that does
not
seem to be widely used.

Carl-uno I think that we should put 'exotic transports' on the agenda of an
IPP
meeting soon becuase there is obviuosly interest and it is not in anybody's
interest to have this fragment into lots separate efforts.

A last IPP meeting, I can see you discussed the topic 'IPP over other
transports'
and that Paul Moore metioned the infrared transport. In i-data we are
working on
the new wireless technoligy BlueTooth. I think in a few years you will not
anymore
see the use of infrared soulutions anymore, but it will be BlueTooth.
Ericsson,
Nokia
and the PDU's are going to implement BlueTooth in their products. In i-data
we
are working on a LAN profile to Bluetooth as well as on a Printing Profile.
Our
solution for printing over Bluetooth will be to use IPP over WAP. WAP is
implemented
in some mobil phones today, and will be widely spread by the years. WAP
looks
like
a lot like HTTP. So I think it would be interesting to run IPP on the top of
WAP. You
would then be able to print from your PDA or mobil phone.
