you might try glTexSubImage(..)

you can cache image data in system memory, and replace part or all of the current bound texture object with this command..check the red book for details..

if you''re using the same texture for more than one surface watch out, any changes made to the texture object will appear in all surfaces using it..if that''s the case you''re better off doing decals..
