should be able to, it's pretty well architected. 

I did a talk at Cassandra EU last week about the internals which will be helpful, look on
the Planet Cassandra site it will be posted there soon. (I did the same talk at Cassandra
SF this year as well.)

If you are looking at the code the getColumnFamily() and apply() functions on the o.a.c.db.Table
class are the read and write calls you would want to use.
