Yes, that could easily be arranged. I've tried to be careful and nowhere asssume that the regular caps were precisely numbers 32 through 63.

I'll do this now for version 0.4.2, which merges with your own filesystem support. I made one noteworthy change to your code, by the way, which is to disable the "permitted" (=forced) set of capabilities on executables whose filesystem is mounted nosuid: I think this is a reasonable constraint, to avoid the attack where a luser mounts a usb key with xattrs in the filesystem or something like that.
