"Viewers" is a terrible term. There is categorically no way to tell
how many people may be "viewing" a particular resource.

Well, ignore the "viewers" problem, people usually tell how many
concurrent requests they are getting from mod_status;
http://httpd.apache.org/docs-2.0/mod/mod_status.html
Right now I can tell that there are 2,527 concurrent downloads from
ftp.heanet.ie, with more requests for
/pub/fedora/linux/core/3/i386/iso/FC3-i386-disc1.iso
than any other. (note: this does not make it the most popular file,
others may be downloaded more often, but this file is both popular
and takes a long time to download on average) ... for example :)
