patching and subclassing securityfilter for my own customizations

Hi,

I've wedged SecurityFilter into my web app and now I want to subclass it to
do some things differently.

In particular, I really like that security filter:

- supports declarative security in a config file

- implements saved requests while intercepting for login

For my own purposes, I want to make it:

- not wrap the HttpRequest, rather use a request attribute to store and get
the user principal.  This is nicer for my view (velocity templates).

- store a backend service object in addition to the user principal

- respond to "remember me" options in the login form

- automatically authenticate with my own persistent cookie system

- mark failed logins by placing a flag in the request

These customizations could be implemented by my own subclass, if the
SecurityFilter class was a little more decomposed with public access to the
important methods.

I'm going to do the modifications myself to make the subclassing possible.

Would the author / community be interested in my changes when I'm done?

Ethan
