Subject: Accessing multicasts from non-multicast enabled nets

When you set up a stream multicast access only, people who try to access
this stream from non-multicastenabled environments get an errormessage
saying.
"RealPlayer cannot show the stream" (or something to that effect).
This is not very good as the player in fact works beautifully, only
their environment does not support Multicasts.

I want to be able to send them an errormessage saying "This material is
Multicast only. Your networks does not support IP-multicast. Please
contact your networks administrator"
or even better, have the system release a stream with a nice voice
telling the would-be-viewer that his player works beautifully, only his
Network does not support IP-Multicast.

I believe that something like this can be achieved using a CGI-script
thet checks whether the requesting IP-adress is within the multicast
subnet, but I haven't seen it done. Does anyone know how I could go
about this? All ideas are good ideas. Otherwise I will be overloaded
with emails from people whi think the player sucks when it is actually
their network that is inadequate.

If anyone has any ideas on this please post it!
