Using Second Life for training

I have been following Second Life for awhile now just watching what happens.  Personally I feel the potential for the environment is huge we just need to get over the gambling and sex that currently occupies a majority of Second Life.

This is changing, there has been several conference run in Second Life, Cory Doctorow has done a book reading, people are even conducting business within the environment.

Today I noticed Robert Scoble posting about using Second Life for corporate training, an interesting use of the environment.
