It must be based on Plack. This will allow it to run on most webservers, even shared hosting such as Dreamhost, which allow FastCGI scripts (see Plack::Handler::FCGI).
The dispatcher will be Web::Simple, which has the cool feature of subdispatch. Unlike other micro-micro-frameworks, Web::Simple doesn't have a templating system built-in.
Yes, static files can be served just fine with Plack — see Plack::App::File and Plack::App::Directory.
[TODO] Things that are kinda like mod_rewrite:
It would be nice if it could support a huge variety of different markup languages, and be configurable to select one.
But for now, I'm just interested in MultiMarkDown.
Eg. It would be a framework. And the configuration would be in delcarative style. But it could include Perl code that would get called at proper times, eg: When doing the markup ⇒ HTML conversion.
It could also set configuration parameters, such as whether to use inotify or not. (inotify may very well be inappropriate on massively-shared-NFS-servers like Dreamhost)
