git-annex: multiple web remotes?

[Olaf TNSB]

Hi joeyh and other annex-types,

I've got a couple of questions regarding the web special remote in
git-annex.

Firstly, I was wondering if it was possible(*), or too technically
difficult(!), to have multiple web remotes for files in an annex. For
example, I can find a few different links for Graham's 'On Lisp' and I'd
like to have my X local copies in annexes and also a couple of URLs for the
book in my annex.

Second question, & it's probably a RTFM, how do I find out what URL is
associated with a file?  'git annex whereis file.name' only tells me 'web'
as the annex location.

Thanks for any help,

Olaf

(*) Yeah, I know I can submit a patch, but I have enough trouble
_compiling_ git-annex, so hacking in Haskell is a bridge too far
currently!  ;)
