Not in my case. I accept to sacrifice some features to keep my blog static. Maybe something on the client side that pulls comments from a public source will do. Maybe even just "email me if you have a comment and I'll include it here".
Also, would it be nice if Comments network integrated comments on their own when the thread is closed? So you can just comment on the site itself (once the network comments are closed it'd basically be an alternative to Disqus).

It could do with some more love, to add nested comments, but otherwise it might be of interest.
