I think we would like to do this sometime in the near future, but I don't know exactly what time frame fits in yet. There is a lot to do still, and we also need to get a 4 release of both Lucene and Solr out to users soon. It could be in a point release later - but it's open source - it really just depends on what people start doing it and get it done. I will say it's something I'd like to see done. With what we have now, one option we have talked about in the past was to just install multiple shards on a single machine - later you can start up a replica on a new machine when you are ready to grow and kill the original shard. i.e. you could startup 15 shards on a single machine, and then over time migrate shards off nodes and onto new hardware. It's as simple as starting up a new replica on the new hardware and removing the core on machines you want to stop serving that shard from. This would let you expand to a 15 shard/machine cluster with N replicas (scaling replicas is as simple as starting a new node or stopping an old one). - Mark Miller lucidimagination.com
