Personality Types in Technical Teams?

Any opinions on evaluating personality types (specifically, using the MBTI) in technical teams?
I’m specifically interested in how the different types within my group can be utilized to create and facilitate effective technical training – for example, if I’ve got a trainer who is more Sensing and Feeling, that person may be less able to get a technical point across to an end-user who is more Intuitive and Thinking.

My group is small, and is focused on IT training, so we are technical in background, but can be “touchy-feely” in our delivery & communication.
