How do I make nodes of a specific content type appear in raw text form?

I don't know if someone had a similar problem in the past (I did some research but didn't come up with any solution) so here it is:

I want to create a content type whose nodes will be shown as pure text: no HTML no nothing... I just want a special field of the node (it could either be the body field or a custom field that I'll create) to be printed.

My first thought was theming but I guess that the rest of the theme as described in the page.tpl.php will be printed too and I do not want that.

My second thought was to use txt files. The problem with that is that they will not be so easily manage-able and I really want to use drupal to manage all the nodes that I will create.

Anyone got any ideas on this?

Cheers and thanks for any help that you can provide!
