There should be very little overhead in creating many proxy objects that share the same handler. A proxy object is just an empty object with a hidden reference to its handler. Besides, if you want to reliably proxy multiple objects, you must instantiate a proxy per object anyway, otherwise you may get in trouble with object-identity. A single proxy object that proxies many different target objects would have only 1 object identity, so all the proxied targets would appear to be identity-equal. Cheers, Tom
