This sounds like we can make it work. Does the new multi-contacts enhancements to AR 9.0 (where each contact may have an email address) have an effect on how this works now or will work in the future? Seems like you could set up a unique (but consistent across customers) contact to hold information on who gets confirmations, who gets statements, who gets invoices, etc. Or maybe I'm not understanding how the new feature will work.
