OK, that is encouraging.  I'll take another pass at it.  I succeeded
yesterday with an in-memory only InputFormat, but only after I commented
out some of the split referencing code, like the following in MapTask.java
    if (instantiatedSplit instanceof FileSplit) {
      FileSplit fileSplit = (FileSplit) instantiatedSplit;
      job.set("map.input.file", fileSplit.getPath().toString());
      job.setLong("map.input.start", fileSplit.getStart());
      job.setLong("map.input.length", fileSplit.getLength());
    }

Yes, that code should not exist, but it shouldn't affect you either. 
You should be subclassing InputSplit, not FileSplit, so this code 
shouldn't operate on your splits.
