MH rigs work in blender [will need rigging for poser/ds, try autogroup{poser} be prepared to fall off chair laughing] but is better rigs MORE WORK, just saying MH to blender ....nightly builds give a 95% or better chance of it working [both update so much it can be annoying to get them to sync just keep trying]

maybe give us more clues as to what you want to do ?? special tools do special things rather well.........universal tools do EVERYTHING if you can stand on one hand while .......... lol ;-) [honest I lurve blender ........not just cos its free..........but if you find something it cant do you can write a python script to twist its arm ]
