hi Anthony,
Thanks for getting in touch about metalinks. I've personally never heard
about this before, but it sounds interesting. The first question that
comes to mind is - how many user end download clients support this format ?
And, if we are to publish these, we'd need some means to generate them
automatically, perhaps a hook into the mirror-monitor scripts. But thats
a future issue.
I am cross posting this to the CentOS-Devel list, so that more people
might be able to get involved in the conversation. I suggest you
subscribe to that list (
