Just adding a TODO.
I opt (for years) for removing it - it does at least nothing for us.
Even worse, it does not work. As it is, it tries to open your MAC as a URL, which fails for obvious reasons.
I honestly don't think I've even looked at this file until now.
its disabled somewhere anyway - long ago - probably in llstartup or llappviewer. Its purpose was to update the Hippo Viewer - in no way Imprudence did or would ever want it to do.
Actually, still getting a warning on startup that CURL can't connect to something that looks like a MAC which I suspect this code is doing. I'll track it down later and remove it and this file.
I grepped for it, there is an #include in llappviewer.cpp however not in any cmake file - so its not compiled and also obviously nowhere used. Your CURL error must be from something else.
Away goes this file then.
