uPnP information

Hi guys,
I am trying to find out some information on uPnP ,
specifically on Linux but everything I come across is geared towards
dynamic configuration of devices via uPnP.

As far as I understand it, uPnP is a competing protocol to mDNS with
much better support for Windows machines ? So in theory this should
allow me to advertise a service for a machine and have it discovered
on a windows network regardless of the  IP address that it is
assigned.

What I would like to do is expose http as a service on the network
without having to know what IP address is given to it.

For example on the new mactel machines that use mDNS you give the box
a hostname (i.e bobsmachine) . and you can type bobsmachine.local into
safari and if you have an http server running on bobsmachine then it
will serve up pages etc.....

Now i basically want to do the same thing with uPnP so that windows
machines can do the same.

Is this possible or am I miss understanding what uPnP is for?
Can anyone direct me to documentation showing how i would go about
doing this or how i would create a profile that would mimic this
behaviour ?


thanks in advance.
Andrew
