It is noteworthy that this was created by Phusion, the same people who created Phusion Passenger (mod_rails) and Ruby Enterprise Edition. Basically, a company that really enjoys solving high-profile problems related to Ruby. (First, Rails is a pain to deploy. Then, Ruby is a memory hog in web-application applications. Now, Debian hates RubyGems.) From my perspective, their work is high-quality, and increases my confidence in this 'product'.
