Do you mean nbd, the netblock device?

Perhaps the Ultramonkey-L7[1] stuff may help with that.  I'm pretty
sure it's all geared towards web stuff, but with a bit of work could
probably be made to work with mysql as well (I'm not that familiar
with the workings of recent mysqls, I'd usually favour postgres for
serious work, but perhaps look at the mysql docs to see what options
they suggest for the type of solution you are after).  Anyway, this is
probably not the ideal way to do it: in my opinion, it would be better
only to use load balancing between the clients and the frontends of
your system if you can.
