First the research links:

IPv6 spec (look for 'jumbo payload'):
http://www.cs-ipv6.lancs.ac.uk/ipv6/documents/rfcs/archive/rfc1883.txt

IPv6 Sample C# Client/Server
http://www.codeproject.com/csharp/ipv6.asp

I am developing an application where I need to broadcast information to
clients. I have hit a 64K limit in UDP broadcasting. I am not exited
about coding around this problem. It appears IPv4 uses a 2 byte length in
the header of the message which translates to a 64K Message limit.

It looks like IPv6 may get around this 64K message size problem by using a
"Jumbo Payload" (check out the IPv6 spec link), it could save me a good deal
of coding headache if I can get a IPv6 Broadcast to work with Jumbo
Payloads.

I need help answering the following questions:
* Can I use .Net IPv6 broadcast in place of IPv4 UDP broadcast? It looks
like the IPv6 structure will broadcast properly on IPv4 equipment for the
same subnet.
* Does the .Net implementation of IPv6 implement "Jumbo Payloads" so I can
get around my 64K message length problem?
* Does anyone know how to do a IPv6 broadcast in VB.Net. (Got a sample?)

I could not find any .Net samples working with IPv6 broadcast. An example
of VB.Net doing a IPv6 broadcast would be ideal, but a C# broadcast sample
would be ok too.

Thanks so much!

Greg.
