The key for that certificate is going to be extremely valuable, and
your client is going to need to put a copy of it on every server in
their domain that wants to use the certificate.

If this is just about being able to put multiple SSL virtual hosts on
a single ip address, I think it's much better to use a "unified
communications cert" that uses the X.509v3 Subject Alternative Name
extension to apply a single certificate to multiple domain names.
