I like #42, can you play with the typography a bit. this is the altria logo, which is close to that one http://asianchambergala.org/images/altria_logo.jpg would like to see it more colorful, different squares different colors, don't put too many colors
#106 - try exploring other directions, think outside the "box" keep with the technology but stay away from a web 2.0 look. Play with different fonts and weights. Treat the typography as part of the logo, alter the type and make it work with the mark.
sorry, i had to revise after it someone showed me a logo out there that was kind of similar, enough that i felt that it would not be in your best interest. having said that, i think a couple of these are better since they are simple. let me know your thoughts. i can get closer to the one you were liking to a point
