Significant parts of the spec is (as far as I know) impossible to 
implement in IE using plain javascript. More can be achieved by using 
HTC's (which are not a type of plugin btw., but are loaded dynamically 
just like js files, and with the same security restrictions). Still, a 
lot of features like the file upload extensions, new events which 
bubble, new pseudoclasses etc. cannot be supported in IE without using 
binary extensions.

I would guess around 100K to implement the parts of the spec which is 
implementable. But maybe if the code was as succint as possible, no 
superflous whitespace etc., it could be compressed to 30K.
