Any progress on a DIGEST hack

[dons]

Has anyone made any progress on creating a hack to deliver digests in email? What I need is the ability to have my users elect to a)get every post as an email(current), b) get a summary digest in email once a day or c) get nothing in email.

Has anyone started on anything like this for 2.0?

i am working on something, slowly, the other way round which does everything by email both sending posts and receiving them but started on the sending first (as it is harder). It will take quite a long time to finish though and i am basically waiting to do some of it until the final is out.
