SolrCloud should be indistinguishable from Solr w/ replication in
terms of functionality, so this should work just fine.

SolrCloud should actually (and I'm kind of guessing here) give _better_
consistency than Solr w/ replication. Consider 4 slaves all with a polling
interval of 10 minutes that just happened to start up every 2.5 minutes,
and a master that committed every minute. The slaves would always
be out-of-step with each other by up to 10 minutes.

There's a lot of work in SolrCloud to make sure that all the replicas are all
caught up before they start serving requests. An update to SolrCloud
gets passed to all the replicas before being searchable.

So just go for it <G>...
