I have had the service stall out on the server a few times (I have been using it at one site for about 5 months), and for the last week I haven't been able to get the client to work with the deerfield website and retrieve the current version (not that it needs it now, but the site still gives me errors). I'm a bigger fan of [url=www.tzo.com]TZO[/url], and I've been using it for about 2.5 years now.
