I was sort of thinking it was two different issue. I think the sky condition server is for sure the approach to develop and is there to address the scheduler sky condition variable. The other issue is just to read and display the resulting value, which I assumed Lucaz was looking for. I don't know much about perl but I think that Lucaz could use a call to the supplied perl script from inside ACP and it would go and retrieve the value he is looking for. Sort of like a function call. He would have to supply the required arguments the perl script is expecting. I just don't know if that could be done from the html of a tiddler or an ASP script.
