Complementary mod-rewrite url parameter transformation scheme

Imported From: http://groups.google.com/group/in-portal-dev/browse_thread/thread/2e6ea47ce3fd5674#

I propose to add ability (on/off via configuration variable) to transform all url parameters (except of "env" of course) in form "/parameter_name/parameter_value". For example:

before: http://www.site.com/path/to/template.html?size=large&page=14
after: http://www.site.com/path/to/template/size/large/page/14.html

Don't know, how useful this could be though.
