Mike,

It's difficult to answer this. Instantons wouldn't probe the large scale topology of spacetime, because they are so extremely localized. On the other hand as probes of the microtopology of spacetime - quantum foam and the hypothesized radical topology change at the Planck scale - instanstons have the disadvantage of being classical. Not to say some semi-classical approach a la Hawking mightn't use them for that.

Regards,
Dick
