I would like to add a few things:

If the tool is in apt we still need to know because we create a .deb package which contains a link to the original package and also contains a proper menu link for the backtrack menu.

If there is a tool you want and it is not available via apt we need to know that as well. Your tool request may not make it onto the bt4 .iso however we are going to add lots of extra and optional things to our repo which are not otherwise available except from source.
