Update:
about the remote stuff: "The Quota module provides access to file system quotas. The quotactl system call or ioctl is used to query or set quotas on the local host, or queries are submitted via RPC to a remote host"
Comment on Re: patern matching whitespace, / and others
I'm looking over the source for it, but sadly it doesn't appear that I can figure the important guts of it out, and, as mentioned before, I cannot be sure all of the hosts this will be running on will have it installed....
And this also needs to work on solaris, irix, and linux(x86), which makes that little bit it compiles tricky for doing the use lib thing
jcpunkall code is tested, and doesn't work so there :p (varient on common PM sig for my own ammusment)
just write a little setup script which checks if "Quota" is installed and if not, install it using the version in your self-made setup-package.
reinevnting the wheel can be a pain; and when i look at your regexp above, it really is. :)
