Lorne, rather than the polling, you can go the other way as talked of in
relation to the TuneIn API:
Have now and next run a script and update a file with the metadata. Have
the script get the metadata from the file and wget or curl a GET from an
apache server at the transmitter site.
wget $URL1 -O /dev/null
Then let that Playing,php at the transmitter end do what it needs to to get
the data to the RDS.
You can see the results of this being done here:
all the best,
