A very quick summary: ip_vs_user_sync_simple is userspace,
the ipvsadm controled daemon is in the kernel.
Slightly longer summary: I worked on the synchonisation code
for a client, and we decided to make a user space daemon
to match up with some requirements for that client. In a nutshell,
its easier to write user-space code than kernel code. It also
addressed a number of concerns I had with the in-kernel code
at the time. However, they have all been fixed now.
So unless you desparately want to do some hacking, the
in-kernel, ipvsadm-controlled daemon is my recomendation.
