Is downloading every module really that much of a hassle?...

Not really, but it seems that this information should already be out there. As far as I can tell, it's not. So I'm in the process of generating my own list. What I'm doing:

• If there is a .meta file available, I use that,
• otherwise I download the module, extract the Makefile.PL and do some simple parsing using a module I wrote called Module::MakefilePL::Parse (since Module::Depends uses modules which do not work well on Windows -- ironically this was one of the reasons I started on this project)
