What about:

re = /((?@<paths>(\/\w+)+\/)(?@<filenames>\w+),?)+/

m = re.match("/usr/local/bin/ruby,/bin/bash,/sbin/reboot")

m['paths']     # => ["/usr/local/bin/", "/bin/", "/sbin/"]
m['filenames'] # => ["ruby", "bash", "reboot"]

My regexps may be off (didn't test :)), but you get the idea.
Wouldn't that require multiple regexps with scan?
