OK, that makes sense, so I need to browse for the subtype right?!
So here is the next question, is this a valid subtype:
"225_0_10_100._ftp._tcp"?
I think that avahi insists on having a leading underscore but is it an
avahi think or is it in the zeroconf spec?

The Mac tool is not browsing a specific Multicast address. It's just
using the DNS-SD subtype feature. You're browsing "_ftp._tcp" with a
subtype of "225_0_10_100". All packets are still being sent to the
link-local Multicast address assigned to mDNS (224.0.0.251).

Well, if the mac util dns-sd can browse a specific multicast address
(dns-sd -B 225_0_10_100._ftp._tcp) then I would expect that it's a
zeroconf functionality. They did came up initially with zeroconf,
right?
But nevermind, I guess I'll have to snoop the multicast address
myself.

I don't have any documentation to contribute but I can explain the
logic:
A large amount of file servers (it's not really ftp) are being split
into clusters, when a file is added to one server in the cluster it
is
being replicated on different nodes within the cluster (for
availability
and backup). The construction of clusters gives the possibility to
have
different clusters for different purposes on one local network.
If this functionality is not supported on the client side will it be
possible to configure the daemon to listen to a specific multicasting
address?
No. The mdns spec only defines 224.0.0.251 as mDNS multicast group and
that's why we use it. I see no reason to support a different address.
I am sorry, but I don't really understand what you are trying to do. I
kind of get the feeling you are misusing the mcast functionality for
something where VLANs should be used instead.
