Module development and code questions

Most of you are probably familiar with the rating system employed by Netflix and others. Here's an implementation by ITConversations: http://www.itconversations.com/browse.php

Both Netflix and ITC are using something apparently called "StarBar", various pieces and versions of which can be seen here:

Hi Drupal Gurus:

I was hoping that somoene might be able to help me w/ a little problem. I have been flirting w/ the idea of creating my own nested tree structure as part of a module I'm developing. The structure would essentially complete with the taxonomy functionality except be localized to a $user->uid w/ the ability to be shared and or public.

How can I let users create their own secure (not site wide) taxonomy / tagging system for content?

I was hoping that this could be accomplished w/out the need for duplicating development.

Ok, I'm a total newbie at drupal development, but I know some php and am a capable programmer in my own right. Perhaps some of you can help me.

I would like to create a module that would have the following features:

I've created module which provides a wizard to assign a geographic location to your website and register it to geoURL.net.
It does also enable a block with a list of selected nearby websites around your page...

The wizard is implemented with the help of ajax, and might be a nice example if you like to implement something like that for yourself.

Ok, hopefully this is quick and I just missed something. I am building a click-edit Google map, and everything is alive and functions except for 1 element -- saving marker data. The difficulty (as I see it) is a choice between two ways of moving marker data.

Layout:
Map table -- has/stores map specific settings, center, zoom, etc
Marker table -- has/stores marker data and is keyed to a map entry based on $mapid
The ability to reuse markers without having to re-enter them is an unexpected benefit of this design.

Methods:
1. XMLRPC all the way. I click a point to create a marker, I edit that marker inline in the javascript, and I can save it directly vi XMLRPC. Piece of cake. Not much code, not much effort. The problem is going to be one of access. I can write XMLRPC code to dump all markers, or even in a worst case scenario, the problem of map or location based spam becomes a nightmare. The only token that I am aware I have access to would be document.cookies.PHPSESSID, but I don't know how that relates back to anything in Drupal that would let me authenticate and verify a content creator. The second problem with an XMLRPC only method is the fact that any new markers will/can get updated in a marker table before the map node has a nid assigned (or even exists for that matter)! The work around for that would be a staging table where orphans get deleted after a specified age limit, everything is keyed on PHPSESSID, and markers that belong to a map node that actually gets created get migrated to the live marker table when the submit occurs. Gut feeling tells me this is the method I should be trying to use, but I really don't have much of a starting point as far as Drupal and user verification are concerned.

Look more likely that I have thought up !
add in module flexinode an opportunity to place fields according to html a pattern and

add an opportunity of automatic scaling of pictures in a floor image

here new the module
