I apologize if this is the wrong place for this. I have been working on
building a rendezvous php module, and have a proof of concept. I've been
developing it on windows, but I think it should compile fine for the
real platforms. Feel free to point and laugh, it isn't amazing code.
sample usage:

<?
$conn = rendezvous_register_service(
"_http._tcp" //dnstype
, 4500 //port
0// optional - interface.  0 means all, -1 means
local only.
);//returns a rendezvous connection resource
$servers = rendezvous_browse(
"_http._tcp" //dnstype
, 2 //optional - timeout in seconds
, 100 //optional - timeout in microseconds
, 0 //optional - interface, see above...
);//returns an array of hosts that responded.

echo("<pre>");
print_r($conn);
print_r($servers);
echo("</pre>");

rendezvous_unregister_service($conn);//stop advertising
?>

Hi

first. pecl-dev@lists.php.net is the right place for this

second. there's already a zeroconf extension at pecl (based on howl),
which does some rendezvous stuff. Maybe you could join efforts with
them. http://pecl.php.net/package-info.php?package=zeroconf

But yes, rendezvous support in PHP could certainly have its uses.

Looks pretty clean..

I've never worked with Rondevouz, I understand it's something like a
link-local multicast version of portmap?

I see that it requires linking against an external library, how is that
library licensed?  Are there unix versions of that library available as
well? (the zip only contains a windows .lib file)

More imporatantly, do you have a link to the site you got that library from?
(Save the rest of us some googling)

It sounds like something that would fit nicely into PECL.  Be sure to bring
it up within that forum.

Interfaces are numbered from 1 then?  Would it make sense to use a "Network
Device Friendly Name" under windows? (performing the lookup silently using
Win32API calls)  That might not be a wonderful idea as there's not much in
the way of POSIX standardization when it comes to mapping unix interface
names to interface numbers...

It uses multicast dns queries and replies to advertise services.  it
does only work link-local, although
they intend to add a unicat dns query that will be able to browse
services across routing.

It's based off Apple's rendezvous implementation.
http://developer.apple.com/macosx/Rendezvous/
The license is APSL(Not entirely open, but free).  I'm not sure what the
ramifications of the licensing will be.
I kind of just threw this together, hoping it would work.

I think I'm going to move this discussion to Pecl

To be honest, I'm not sure about the interfaces thing. Right now, that's
just getting passed directly to the underlying
library.
