I'm not sure what your tring to do ultimately, but if you do RTFM you see:
mount /mountpoint -o remount,rw do stuff mount /mountpoint -o remount,ro
most flags can can be changed ....
If you want to do it on a filesystem that contains /etc (ie /etc/mtab is, or will be, on a readonly fs), then you need the -n switch too.
