First of all test results. Test conducted at -6 level on my PAQ_TestBed_Small.tar file which contains 16 specially selected files to activate all PAQ8px models 
It weights 9 910 784 bytes. There is also nomal larger version - 15 580 672 bytes but its for some special purposes
So here we go...
Code:
paq8px 721.884
paq8px_speed_optimised 713.520
paq8px_sse2_amd 698.816
paq8px_sse2_intel 717.818
paq8px_v58_MMX 653.812
paq8px_v58_AMD_SSE2 637.277
paq8px_v58_Intel_SSE2 635.745
Truly speaking I'm quite impressed with these results on my AMD64 4000+
Secondly. All output files are identical and wildcards are supported so nothing to say - well done !
