Julian Mehnle and I recently got access to the libspf2 repository and with 
(some) help from the previous maintainers are going to work towards releasing 
a new version that brings together the known patches.

The Debian package has also accumulated a number of patches:

http://packages.qa.debian.org/libs/libspf2.html

I'd be interested to hear from everyone who has patched libspf2.

I'd like to get:

1.  A copy of the patch

2.  The problem the patch is meant so solve

3.  Testing/production experience with the patch
