Summary: Support for WIFI enabled cameras

Initial Comment:
There are a number of new cameras from Nikon (Coolpix
P1 & P2), Kodak (?) and others that have inbuilt wifi,
it would be great if gphoto supported this interface ...

the 15740 standard is available to us via a ALPHA version of  
the same standard ... and we implement it for the USB part. 

we just need to know the interaction needed for PPTIP. 

You said the Nikon P2 will support it, right? Since with 350 Euro 
lioke amazon.de says it is not that expensive I can even buy 
one... 
 Do you know when Nikon will release it?

Sorry don't yet have such a camera to sniff traffic from.

Also don't have the spec/reference documentation however
fotonation quotes an ISO standard # 15740:2005 which can be
downloaded from www.iso.ch for a price (CHF 188 ???) ... if
this is likely to give the info reqd and my gives me a green
light i'm sure i can acquire a copy.

There's a usenet thread
(microsoft.public.standard.iso15740), not active recently,
and i gave up searching after a the first few dozen pages of
offensive spam ...

I have been looking at it, on the paper. It looks like we
need to encapsulate PTP over TCP/IP on a Wifi link. But we
need to evaluate how that PTP link is encapsuled, and how
the Wifi connection is handled in term of UI. Maybe it won't
as simple.

As Marcus said sniffing a sample traffic might help. Doc
would be even better.

I also can volunteer if you need development to be done....

what would be a good first step if you already have such a 
camera would be to capture the network data flowing between 
host and camera using some kind of wireless sniffer.

Well, wifi setup is present, camera only + its windows software is 
sufficient. 

I tried finding the PTPIP spec on fotonation.com, but it seems to be 
given out on request only. Or do you have found a free download 
for it?

The ptp-ip specs. and a reference implementation are at one
of the co-developers sites (www.fotonation.com) ... Nikon
are the other half of the equation.  Micro$oft have
apparently worked with the above to develop an enhancement
called MTP ... would seem that support for these protocols
will become a useful addition to gphoto's arsenal as more
camera's go to market ... but I didn't look into whether
they're 'open' specifications (probably not).

By hardware you mean camera only? or wifi ap and cards also?

We would probably use the Nikon Coolpix P2, this model OK?

The problem is also the documentation of it. The slides are not 
very detailed ...  

However we could reverse engineer it. 

(I tried to become a member of I3A twice, without any feedback.) 

I would volunteer to implement it if you can provide hardware.

It is possible that my company would be prepared to provide
a camera/cameras and sponsor the development as the
functionality could potentially solve a riddle we are
working on.

Above and beyond the cost of a camera what would be entailed
financially? and have you any idea whether anyone would be
likely to find it interesting enough to take it on?

we'd need a camera to do any work... anyway. feel free to
commit a patch or sponsor the development.

 I'm trying to acquire one of these cameras to see if it
does what I need out of the box, but it would be more
likely too if gphoto could talk to it!

I was under the impression that micro$oft et al had
agreed an ip extension to the ptp protocol (ptp-ip)
hence manufacturs suddenly starting to release wifi
digital still cameras;
