Roles based login structure 2.0

I want to create a Visual [login to view URL] 2.0 (eventually compatible with 3.5) and SQl server 2000(eventually compatible with 2005/2008) role based login structure. I know how to use the Asp.net inbuilt controls but want someone to come up with a sophisticated template i can use for my projects. Project documentation or user guide will be required. Should be able to do the following 1. redirect if user not logged in 2. role based structure(so specific pages for specifc users with specfic roles) 3. CSS styles sheet/themes(if I change one styles sheet..should reflect on entire site..includig adding menus etc) 4. Admin section for administration of users, their roles and access for the specific users -- password recovery -- is active or not. 5. should be able to login and remember their password to come back later. 6. Completley gui based strucutre(not typically text based) More stuff to be added as work goes along. I want this project not be basic (even I can do that myself), I want this completely ajax enabled..with great looking GUI (which I should be able to edit eventually using styles sheets later) and with good user friendliness. [login to view URL] login is something I like..nothign changes adn when user click on my account..the ajax window pops in and he is in. [login to view URL] is another design I like. Don;t know much about webparts but would like to learn and incorporate one. [login to view URL] ## Deliverables it has to be in Visual [login to view URL] and Ajax. GUI will be stressed. Please show your samples and should be available on MSN.
