sorry I typed it to quickly.
[computer bonjour name].[_device-info._tcp].[domain]
but I get error -72004 when i try it. :(
witch is an invalid parameter.
I've searched the internet for _device-info.
and apparently i'm not the only one asking about this feature, but no
one seems to be getting an answer :|
Oh well... Discovery time :)

can you see the model=M68AP ?
the service reference here :http://www.dns-sd.org/ServiceTypes.html
says
device-info
Device Info Stuart Cheshire , Marc Krochmal Not a service type.
Special name reserved for DNS-SD device info.
So the query would be .
[computer bonjour name].[service-info.tcp].[domain]
resolve that, and you get your model info.
This is just speculation for now but i'll try it tomorrow and let
you guy's know ! :)
I. Savant thank you for being curious as I am :)

there is not way to know beforehand if the servers are going to be
present
So it makes sense to ask the server what it is. when Bonjour
declares it's presence.
or when the SMB server broadcasts.
The icons for every possible mac model are local to the computer,
if you have a Mac.
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/
I suspect that the icon in the reply from the FPGetSrvrInfo is
useful for other platforms.
because with the model number, there is pretty much no more
information needed to
associate an icon from the local resource.
The only problem I find it VERY complicated for such a simple
feature.
to have to implement sockets UDP or TCP "have not gotten a reply
yet".
Just to get an image to show up on screen :) is quite an overhead :)
Perhaps it would of been nice to add the model number of the
machine to a NSNetService(Bonjour) TXT record.
Instead of having to uery the host directly. IMHO
I might be wrong, what do I know :)

The AFP client sends the FPGetSrvrInfo command to obtain server

The FPGetSrvrInfo command returns server information including
the following
server parameters: server name, machine type, AFP version
strings, UAM
strings, volume icon and mask, a bitmap of flags, and optionally,
a list of
available Open Directory names. For descriptions of server
parameters, see
FPGetSrvrInfo in the Reference section.
Neat! That seems an odd place to put that functionality, but
hopefully it'll be better-placed when all that stuff is eventually
cocoa-ized. Thanks for the follow-up. Very informative.
