Park Place, an Amazon-S3 Clone in Ruby

Via RedHanded:

Park Place, a clone of Amazon's S3 (Simple Storage Service.) It's written entirely in Ruby, with heaps of help from the Camping 4k web framework. Oh, and no SOAP support to speak of.

gem install camping --source code.whytheluckystiff.net
gem install mongrel activerecord
svn co http://code.whytheluckystiff.net/svn/parkplace/trunk parkplace
cd parkplace/lib
ruby parkplace.rb

Great. Your own private S3. Now you can try all S3-based solutions for free.
