Oh, I thought ext2online (which is mostly just an ioctl driver for the
kernel resizing) was part of e2fsprogs.  Was that only in the RH/FC
e2fsprogs 1.36 release?

Maybe you are thinking of ext2prepare?  It would probably be as good
or better to use the resize2fs itable moving and then the e2fsck code
for recreating the resize inode.  That would avoid the addition of
a whole bunch of duplicate code to e2fsprogs.
