thinking loudly - FreePascal and Fastcgi

Morfik is precompiling the application into an cgi using pascal (fpc)
I was thinking what if the fastcgi can be used to run an pascal program precompiled with lazarus(fpc)


The main issue is that main scripting languages migrate to fastcgi: php , python, perl
and light httpd servers (nginix,lighttpd,apache+fastcgi module)

Why they migrate ? because apache threading doesn't work for scripts and we are back to cgi and share nothing architecture (kiss philosophy )
