Untested. Worked in 2010.
Go to the site that has the list view you want. Add a content editor webpart with the following:
Now you can export the webpart you want.
Next, open the .webpart file in notepad and look for
<property name="WebId" …>all_zeros_guid_here </property>
Replace the zeros with the GUID of the site the list is on. You can get it by going to _layouts/sitemanager.aspx When you hover over a site in the right side, the GUID is displayed at the bottom left of the window. ScreenCapture it and type it in.
Save and upload webpart

Gotchas apply and include:
Only within site collection; Not tested with all list/lib; Will error while you allow editing of content type on target list
Alternate methods to aquire site GUID, from Mike Smith's Tech Training Notes
1) Wiki home page:
Works for SP 2010 only: Display a Team Site home page (a wiki home page, home.aspx) that has at least one list web part, view the source of the page (right-view source) and search for "RelatedWebId" (you could temporarily add an Announcements or library web part to the page)
2) Tree View:
Works for both SP 2007 and SP 2010: Go to Site Actions, Site Settings, Tree View and enable Tree View. Then go to any page, view source and search for "ListNode:"
