geo views2

Hi all!
I'm building a site around geo module(6.X-1.0-alpha2). Now, i need a proximity search.

Here, http://drupal.org/node/606342#comment-2160156 there is an extremely usefull argument handler for location module in views.
I'm new to Drupal, but i was thinking about porting this handler into geo module. (this would also be a good exercise in learning Views..)

However, before starting, anyone knows if there is a similar/better solution to achieve proximity search using views2 and arguments?

Thanks!
