007 et all,
Our CRM tool, which will launch publicly in Jan 07, will have that capability (auto-scheduling expired's etc) provided that your MLS allows RETS access.
Of course it's up to you to play by the rules.. (around here you're not allowed to contact expired before they're actually expired).
The software does a ton more too. Meant to fully automate front end marketing and contact managment, we've put a lot of blood, sweat and tears into this thing. Over two years in the making (and research).
If you're interested in hearing more or potentially being a beta-tester (going on now), drop by
