I've taken a crack at preserving #NCAR 's Java METAR viewer, which is miraculously still up-and-running after all these years. Some reverse engineering of how it ingests data is probably still needed.
I have it up on my #CGHMN site if anyone wants to play with it there:

It's still getting its data from NCAR's server for now (updated half-hourly with a cronjob) but I'll eventually work on REing it and ingesting from a more permanent source.
