LVS is able to provide vitual services. If you can have traffic to
the virtual services routed (from your provider(s)) down each of your
10 DSL lines then you will be fine. You can route the return traffic
either accoding to this or asymetrically. Essentially to do this you
will probably need your own IP address space and more than likely your
own AS number and rub BGP to each of your upstreams. If all of the
links are to the same upstream then you can have the same address space
routed to down all of the lines and do line balancing across the
links. Again, for this to work with inbound traffic you will need
your provider to coopertate. Other than this you are stuck with
DNS round robbin, though using a fwmark LVS virtual service you
could load balance this traffic internally once it hits your network
to ensure that the apache servers are used more evenly.
