[storm] Questions about DeferredStores on twisted-storm branch

[Oscar Campos]

Yeah, that makes sense to me, so I already implemented it on this way.

In my application I have twisted web resources loaded as "controllers", each
resource can have a model object (storm object) attached on it that
represents a database table, each model object owns a DeferredStore (or a
Store) that depends on application configuration.

I'm developing a Web Applications Framework using Twisted, Storm, Evoque and
ExtJS so I think I'll ask a lot around here and twisted lists also.

I get some troubles with DeferredResults but I'm busy now implementing
Authentication, and ACL, so I'll ask when I'll back to the code that gave me
the problems.

Btw, do you guys know any decent ACL implementation (not based on file
system like POSIX one) in Python?, I'm developing it from zero so I'm not a
very big fan of reinventing the wheel.

Best Regards.
