I expect that any patches which break OpenSLP on other platforms will not=
=20
be well-received. :-)

Just to be clear, for IPv4, SLP uses one multicast address. So group=20
memberhsip limits aren't an issue.

For IPv6, it uses groups based on a hash of the address. I just looked at=
=20
the code more, and because of how one mask is set up, it will join up to=20
32768 groups (The lower two bytes of the hash are or'd with 0x1000 as part=
=20
of making the address).

Take care,

Bill
