cannot find a way of having multiple shards in a single SOLR_HOME and single Tomcat. Can this
be achieved?

Yes, it can be achieved. There are a couple bugs when you run try and run more than one shard
from the same collection in a single instance though - they will be fixed in the upcoming
4.1 release.

You simply give the cores the same collection name but different core names.

Later, you can migrate those shards to other servers if you'd like.
