I have added rest of the missing checksums. I think it would be considerably easier keeping them up to date / overloading if they were exposed in attributes rather than hardcoded in the library. Probably the least user troubling approach would be to rely on sha1/md5 sum(s) provided in Apache Cassandra repository - while downloading the tarball, download the cheksum and then compare.
