For those interested in GRIT, I found this link interesting as it explains GRIT, the field testing, dates etc. Reaffirms that IBM hasn't gone into this lightly. I thought that fact that they are asking for feedback to help improve the app probably means that regardless of the outcome they will go with TTB, though TTB may need to accomodate changes. In fact it reads that enhancements may in fact be ongoing throughout the trial period.

Good luck
