This is a feature that I want to implement, called application-based
scheduling. Michael and I used to talk about this to use LVS to
implement content-based switching in proxy cluster. However, it is
not easy to implement. The kernel must have architecture to copy
packets to user-space and copy back, and the servers(and its kernel)
must be changed so that established connections can be transparently
migrated to the servers.
I don't think it is relavant to the problem of T-Online.
