... called http://www.LuckyCal.com. Disclosure Note -- I have no affiliation with the product, I just saw it, met the CEO, and thought that they have a clever approach to the management of location.

In their model, you forecast the opportunity to meet at the same location by including your calendar into the mix. So for example, you indicate a trip to Boston on January 1st. -- You can determine who in your network (or if integrated into your CRM, who of your customers) happen to be in Boston. Moreover, if they are part of your LuckyCal network, you can see if they will be in Boston at the same time you will (assuming they publish their location/calendar too -- which if you are teammates in the same company, you will).

What results is a mashup of location, network, and calendaring that can tie into other data sources (e.g. corporate / industry events, customer / prospects, or even just plain entertainment -- e.g. I'm in town for a meeting, is there anything fun to do in the evening?). That said -- LuckyCal is still pretty young -- as is the whole space of location aware social networking. But it sure seems like this space is heating up.

Thanks for sharing such a great list of new products. I'm on two of these networks myself - but I think that if I had an iPhone (as opposed to a BlackBerry) the utility of the networks would be a bit better.
