fit and company with the appropriate expertise. This creates the potential for extreme costs to unexpectedly rear their head. Take for example our company... we conduct computerized flow modelling studies of fluid handling systems out of our office. On occasion, a need will arise to visit our client across the border to have a meeting and to conduct a visual inspection of some equipment that is part of the modelling. Perhaps some data will need to be collected and pictures taken. In order to accommodate the visit, the plant schedules an outage to accommodate the engineer's visit. The down time for the plant is extremely costly (sometimes in the tens and occasionally in the hundreds of thousands of dollars per day) and very clearly if there is a further delay, the plant will suffer a very serious financial cost. [The use of Nexus cards has eliminated many border crossing difficulties for those who cross borders frequently. However, it would seem that the age of technical specialization carries with it a completely unanticipated financial risk when those specialized firms are in a different country. Is it possibile to create a means of conducting a 'pre-clearance' of an individual in order to mitigate the risks to the plant which may be desperately in need of the expertise that has to come across a border? This is not suggested as taking the place of current border inspection but would utilize a methodology such that a higher level of scrutiny could already have taken
