I have tested this on ubuntu 10.04.4 LTS and Ubuntu 10.10.
Mount the device as "ro".
mount | grep DEVICE
/dev/DEVICE on /MOUNTPOINT type fuseblk
(ro,nosuid,nodev,allow_other,blksize=4096)
With "-t" mount gives back a good error why this does not work.
mount -t ntfs-3g -o remount,rw /dev/disk/by-
Unfortunately neither fuse nor ntfs-3g support remount at the moment.
The "working" rw->ro case is by pure accident and could lead to data loss.

Ok, I see the problem now.
Touching an existant file don't fail
but creating a new file fail.
Same issue with latest ntfs-3g+fuse-lite

Still see no issues with your 2nd use case.

Florent,
Please try to mount ro to begin with and then remount rw.
Mounting rw + remounting ro + remounting rw works
Mounting ro + remounting rw does not work
That is with 1.2216
Second case is relevant since it is what happens in the initrd/init.

Don't have that problem with 1.2216 :
[EMAIL PROTECTED]:~# udevinfo -q all --name=/dev/sda6 | grep FS_TYPE
E: ID_FS_TYPE=ntfs
[EMAIL PROTECTED]:~# mount /dev/sda6 /mnt/test
[EMAIL PROTECTED]:~# touch /mnt/test/test
[EMAIL PROTECTED]:~# sudo mount -o remount,ro /mnt/test
[EMAIL PROTECTED]:~# touch
With ntfs-3g 1.2216 I get the following.
[EMAIL PROTECTED]:~# mount -o ro /dev/sdb1 /mnt
[EMAIL PROTECTED]:~# mount -o remount,rw /mnt
[EMAIL PROTECTED]:~# cat /proc/mounts|grep /mnt
/dev/sdb1 /mnt fuseblk
rw,nosuid,nodev,noatime,relatime,user_id=0,group_id=0,allow_other 0 0
[EMAIL PROTECTED]:~#
remounting ro -> rw does not work
remounting rw -> ro works
[EMAIL PROTECTED]:~# mount -o rw /dev/sdb1 /mnt

Confirmed in Hardy build 28-Feb-2008:
[EMAIL PROTECTED]:~$ sudo mount -t ntfs-3g -o remount,ro
/dev/disk/by-uuid/0A22653721620251 /host
Remounting is not supported at present. You have to umount volume and then
mount it once again.
