[Haskell-cafe] State of the Haskell Web Application Stack

I have been for quite some time trying to assess the feasibility of using Haskell in relatively large, high volume, high availability, long-running web application projects. I have enjoyed learning and using Haskell very much for the past year and I often find myself missing various language features when reasoning about alternatives like Ruby (on Rails). If I can identify the right set of tools for the job, I would really like to take the plunge and make Haskell my standard go-to language in web applications.
Here are the couple of key questions that I wanted get your feedback on:
Do you consider Haskell and its environment of libraries ready for prime time in web app development as defined above?
What collection of libraries would you use in such an effort?
What are the up and coming packages/technologies in Haskell-land you would watch out for?
Also, here are some core requirements that I would define for such a project:
Ease/speed of development in both back and front-ends, minimal boilerplate
Extendability and flexibility in iterative development
Robustness and reliability in production environment
Ability to interface with new technologies in the future: Cassandra, Redis, memcached, etc.
Ease of implementing common/reusable features across web applications: user authentication, S3 file uploads, thumbnail/image handling, exception notifications, etc.
In terms of libraries, I can think of a few key components (as pointed out by several others before) that one would need to arrange:
Choice of server (happstack vs. alternatives)
Templating (xhtml vs. file templates vs. newer efforts like BlazeHtml)
Data/storage layer: HDBC vs. HaskellDB vs. others
I know this is a common topic in Haskell-Cafe, but I have failed to identify conclusive opinions from experienced Haskellers out there in previous discussions. My apologies in advance if this is a blatantly redundant post.
All the best,
