I'm not sure I properly understand your question, but if you define your
virtual services by firewall marks, then the full power of netfilter
matches is at your disposal. For example you can easily distribute
connections from different IP addresses differently. It's not
"application level", but IPVS is inherently kernel-based. On the other
hand, netfilter is capable of doing user-space callouts, which may be
enough for you.
