What is the formula for calculating the distance between 2 geocodes? I have seen some of the answers on this site but they basically say to rely on SQL Server 08 functions, I’m not on 08 yet. Any help would be appreciated.

Use an approximation of the earth and the Haversine formula. You can get a javascript version on the following url, which you can translate to your language of choice:
