[plt-dev] Fwd: [plt-scheme] Download links in PLaneT

Sorry; I've not had time to look into this, and I didn't reply because
I believe that there is some support for multiple sources of packages
that Jacob already added into planet (eg, the way that it will get
.plt files from a local cache when you're offline). Did you find that
code when you looked into what you added?
