[Icecast] Can ices read/stream a remote file rather than a local file?

[claudio b.]

Would it possible to use ices to send to icecast an audio file that
it's not located on the same machine where ices is running, but on
another machine?

I've checked through the source code of ices, and found out that it
uses PERL's read function. Maybe by changing this code I would get my
result?  What do you suggest?

If this is not possible, could ices in some way "upload" the remote
audio file to its own machine (so that, later, it can stream it to
icecast)?

Finally, if nothing of this is possible with ices/icecast, would it be
possible with some other input source or stream program?

Thanks to anyone who spends time and effort in replying.
