PSGI is a API to support. It is a not a "backend" but there are
many adapters or "handlers" already out there to export existing 
servers and environments. By using PSGI, you have access to all
the existing compatible handlers and other plugin-like middleware.

So PSGI does not compete with FastCGI. It is an API, not an environment or
server itself.

The existing list of PSGI handlers includes CGI, FastCGI, Apache/mod_perl (1.x
and 2.x) and several stand-alone Pure-Perl web servers.

The value is in the simple, proven, standardized interface between frameworks
and servers.
