[WikiEN-l] Deletion of articles, archival, etc.

[Flameviper Velifang]

In regards to the "wikiunderground" site, I have a couple questions.
 
Is it directly tied-in to the Wikimedia software? Or is it just a fast-refreshing crawler? If the latter, is it sufficiently equipped to handle all article deletions?

Secondly, this concept raises a lot of possibilities. First of all, the question of deletion itself. Is there a need to permanently delete pages so that only administrators can view them? Or could we have another userlevel (somewhere between autoconfirmed and admin) called "Pageview" where you could view deleted pages? I mean, this might be a bad idea because it would remove the importance of deletion (why bother deleting a page if some users will be able to view it) but this level might require 6 months and 500 edits.
 
Thirdly, a developer might even want to automate this process, wherein all deleted pages are transfered to a subdomain, perhaps deleted.wikipedia.org or something to that effect.
 
Just some thoughts.
