let's say this could be an unlimited resources scenario:
if you had to choose a platform for maximun HA and possibly Active-Active configuration over multiple sites, based on you experiences would you choose HP-UX over Solaris? or AIX over Linux?
real numbers are not intersting at this stage
i would be interested in some reports from the trenches like "HP clusters are too slow to converge" or "stay out of AIX because support sucks" or "solaris clusters saved our jobs a couple of times" (just hypothetical examples, they don't really are that way)

as for the "cultural" side right now we have a strong Win background so every unix-like choice would be rather revolutionary
i'm just trying to address this revolution the most proficient way

openssl_evp
evp(3) OpenSSL evp(3)
NAME
evp - high-level cryptographic functions
LIBRARY
libcrypto, -lcrypto
SYNOPSIS
#include <openssl/evp.h>
DESCRIPTION
The EVP library provides a high-level interface to cryptographic functions.
EVP_Seal... and EVP_Open... provide public key encryption and decryption to implement digital "envelopes".
The EVP_Sign... and EVP_Verify... functions implement digital signatures.
Symmetric encryption is available with the EVP_Encrypt... functions. The EVP_Digest... functions provide message digests.
The EVP_PKEY... functions provide a high level interface to asymmetric algorithms.
Algorithms are loaded with OpenSSL_add_all_algorithms(3).
All the symmetric algorithms (ciphers), digests and asymmetric algorithms (public key algorithms) can be replaced by ENGINE modules
providing alternative implementations. If ENGINE implementations of ciphers or digests are registered as defaults, then the various EVP
functions will automatically use those implementations automatically in preference to built in software implementations. For more
information, consult the engine(3) man page.
Although low level algorithm specific functions exist for many algorithms their use is discouraged. They cannot be used with an ENGINE and
ENGINE versions of new algorithms cannot be accessed using the low level functions. Also makes code harder to adapt to new algorithms and
some options are not cleanly supported at the low level and some operations are more efficient using the high level interface.
