Subj : Byte Arrays in JavaScript

My application reads and writes large quantities of data. I would like 
to present my 'users' with an array like data-structure that contains 
bytes. The present Array object relies on 32-bit jsvals that may not be 
as space-efficient as ideally possible. I could hack together a class 
that emulates byte-arrays, but I was wondering whether there's a nice 
clean way of doing this. Basically, my concern is that how properties 
are resolved may not allow me to stuff more data into each jsval in the 
properties vector. Is there a way for me to store 4 bytes in each slot 
of an object, and still be able to index each element properly?
