Multiple times. The most optimistic estimates are on the order of 4 years. The most optimistic estimates of the return rate are on the order of 6-8 /8s (not the 100% of 22 /8s you are postulating). The legal expenses would be extreme. So, for $ALOT and 4 years of effort, you might get back as much as 4 months of address space. Next? Owen
