Hi Simon,

Just searched for layer menu and came across this site 
http://phplayersmenu.sourceforge.net/. The source looks very small. I 
can not code myself, but maybe someone could use that to make some 
extension. You right that it takes a lot of bandwidth. That is the 
reason I usually avoid menu's like that. Rather use the regular TMENU / 
HMENU and give that some cool formatting using css.
