Some Storage communication related questions

Hi,
     I have multiple questions:

Does hadoop use some parallel technique for CopyFromLocal and CopyToLocal  (like DistCp) Or its simple ONE stream writing?

For Amazon S3 to Local system communication, Hadoop uses Rest service interface or SOAP ?

Are there some new storage systems currently in pipeline to be interfaced with hadoop ?


Thanks,

Wasim
