Actually, both _could_ support online resizing if I ever got
my butt in gear. As it is, only ext2 supports it, but ext3
has untested code to do it for 2.2 kernels.

No, never seen a problem with this. Nobody shrinks filesystems
online, so at worst you might not fully utilize the newly allocated
space. In the end, however, applications rarely check the total
free space in a filesystem, but rather just write until the write
command returns ENOSPC.
Cheers, Andreas
