I believe most high level (non-Thrift) clients convert types to/from 
bytes consistently without additional serialization (XML, JSON, etc).  
There may be a few tricks to working with TimeUUIDs for slices, but at 
least the Java and Python versions appear to be compatible. It's 
probably worth writing a few tests using your target languages to make sure:

Don't see a C++ client, but a quick Google search turned up:
