I played this game before. It started with a Deja Vu feeling, then I noted the company name Spanning Media... and then was reminded about a truly big ripoff. SpanningSync used to be free during the Beta. As with Spanning Tools, this fact was never communicated to users who eagerly sent in bug reports and suggestions on how to improve the program. The rest is history: Spanning Sync had (has?) a price tag of $69 (only for version 1, you're expected to cough up another $69 if you upgrade to version 2) and a subscription fee of $25 per year for those who didn't want to pay the exorbitant price. Luckily, Apple has now included both address and calendar syncing in iCal and AddressBook.
