Belated comment: FIPS 140-2 is used with Apache, both directly as open 
source and as vendor supplied binaries.  FIPS 140-2 is required in U.S. 
DoD and federal government environments (where I do much of my 
consulting work).  That requirement has been in place for years but is 
now actually being enforced.  Many users would like to upgrade but can't 
due to that requirement.

Until a new FIPS validation is available for OpenSSL 1.0.0 it would IMHO 
be a Very Bad Thing to drop support for 0.9.8.  Such a validation will 
require commercial or government sponsorship, as did the earlier 
validations, plus a long lead time.  We get occasional expressions of 
interest but nothing solid yet, but I'm confident it will happen 
eventually.  In the meantime, dropping support for 0.9.8 will force many 
government sector Apache users elsewhere.
