Anyone using Fusemail's Outlook plugin to make your Calendar, Contacts, etc. available via their server? If so, what are your experiences, and have you found it to be worth the cost of the upgraded service plan (min. $18/3mo.)? Is it usable at all with from your Treo?

Any suggestions on other means of getting this functionality (i.e., access to all my Outlook folders, even though I am a small operation with no Exchange Server...not even a fixed IP address)?

Thanks.
