I would have bought a subscription for this right away, as we were discussing rolling something like that on our own for a client.

However, your pricing page being a "mailto" link put me off. Tell the price right away.

Also, what are "advanced" events?

63KB is a little too heavy I'd say. Perhaps rewrite this so it doesn't use jQuery, or at least give me the option to skip it in the tracker js if I'm already using it on my site.

We're still unsure of the cost to run this service as we scale up. We are looking for beta testers to try out our advanced features, so please email us, and we can get you a pro account for free, and start to iterate on the product to meet your specific needs (and lighter weight JS is definitely something we can fix for you).

we wrote something exactly like yours for corporate customers and although I love jQuery, we decided it was best to write it with just straight-up javascript. It was less code than I thought it would be considering how quick & dirty jQuery lets us do things.

Also, if you need to do something like the jQuery css selector style stuff, you might want to look at sizzle by jeresig. It clocks in at 4kb which isn't too big of an overhead.
