[wp-hackers] Excluding page from being listed via a plugin

[Michael C. Duterte]

Hey guys,

I could really use some ideas on this one. Target version is >= 2.0.7 
and I need to exclude some admin-picked pages from being listed on the 
sidebar. I have been looking for hooks other than the wp_list_pages 
filter but couldn't find any. First question is: are there any other 
hooks that I can use for this? Second is: Is it safe to parse the string 
being passed to the function and split them using LI as the separator 
and remove the necessary pages based on the page ID in the link?

Ideas or links will be greatly appreciated.
Thanks
