The main reason not to use FastCGI is that it's a seriously ugly 
protocol. :)  I had it almost completely implemented in PLT before I 
decided that a custom Apache module or HTTP proxying was more sane, and 
then I found the almost-too-simple SCGI protocol.

We've had good success with moving a large legacy system to SCGI, and 
SCGI is proven by others (Ruby, Python, etc.).  That said, HTTP proxying 
is better if you want to do *everything* in Racket code, since then your 
system is no longer dependent on mod_scgi and scgi.ss.  Also, that keeps 
you closer to using the PLT Web Server, which is a good place to be the 
next time you need to rapidly whip up a new Web service or site or 
internal tool or something.
