I put up some patches implementing bitmasks applied to a SliceRange: http://issues.apache.org/jira/browse/CASSANDRA-764
I'm getting crazy column names when I try to use the predicates, though (see "ant test -Dtest.name=TableTest"). Something is getting stringified or otherwise corrupted and I can't figure it out. I've looked at the code for a while and hope it's something really obvious I'm overlooking. Thanks Ted
