Short spiderable URLs like in UBB.classic 6.7 using HTML files (modified from my original suggestion)
Forums (collapsed mode)
http://www.ubbthreads.com/forums/ubbthreads/postlist.php/collapsed/sb5/forum-name/0.html (page 1)
http://www.ubbthreads.com/forums/ubbthreads/postlist.php/collapsed/sb5/forum-name/1.html (page 2)
Forums (expanded mode)
http://www.ubbthreads.com/forums/ubbthreads/postlist.php/expanded/sb4/forum-name/0.html (page 1)

The "sb" part of the URLs should indicate the sort method. For example, sb5 is last post descending, sb4 poster ascending, etc.
