I am developing a "light weight" marker facility with CANVAS.
http://www.polylib.us/polycluster/airports
It still has many rough edges.
A pair of event listeners ("click" & "mousemove") can support ten
thousand markers. Unfortunately, Internet Explorer is out of luck.
VML places a heavy burden on the DOM. Every marker requires an "oval"
element. Every "oval" element requires "fill" & "stroke" sub-elements
in order to control opacity. I may be able to use "shape" elements
with a lot of hops but I have not tried. I believe DIVs will run out
of gas at several hundred. I have not tested the limits.
If anyone knows another way to do it using VML, please let me know.
