Why don't you expose your system as a service?
That way you don't care if your integrated system is at presentation level,
business level, data tier level, as they are only consuming your service.
That is if your are considering the SOA route!

Subject: Subsystems communication
I have a question regarding subsystems communication.
How do I integrate a subsystem with dependent subsystems (possibly remote
ones)?
I found a suggestion saying to call the dependent subsystems Business
Delegates/Fa?ades from the top subsystem Business Object. Is this correct?
I don't feel comfortable with this solution because a think that if you are
already in the business layer, why should I use a Pattern designed to
integrate presenteation-tier clients and system's business services.
