We embed data from ocean buoys into packets on Firenet in a somewhat
standard way.  At least it's the only standard I currently know of
for doing so with APRS packets.

Try connecting up to firenet.us port 2023 and you'll see them.  Port
14580 is the filtered port so you can reduce the feed a bit to suit
your needs.  We inject a _lot_ of objects on firenet.  A typical
dial-up line probably won't be able to handle the full feed.
