I think in general terms, we were having a discussion only the other day, and thinking of possible applications of one form of another of microprocessors, only very generally I might add, but if we thought of an application which would save paying someone's salary on a weekly or monthly basis, then that would be attractive for obvious reasons, you know, that the sort of  when one totals up wages and salaries over a full year then that's a significant saving to be made and therefore it justifies the initial investment cost in whatever the system might be.
