Petshop implementation on ruby on rails

Folks,

I have been trying to figure out whether anyone has done a ruby on
rails implementation of petshop and compared performance against .Net
and J2EE? If anyone has please let me know.

If it has not been done, do you think that doing it would be
interesting? Would it be interesting to you to get a ruby on rails
benchmark performance data? I may be able to get a team in my company
to attempt it if this is a valuable enough exercise. Imo it would be
good and the stats could help on pushing ruby on rails further in some
companies. What do you folks think?

Regards,
Bharat
