Recently, we've made some upgrades to our hosting infrastructure, which is based on Apple's Xserve, Xserve RAID, and Stalker's Communigate Pro email services. One of the features that has been added is the support for Online Calendaring in this release, which we're testing with select users.
This support is added by the newest "Pronto" interface from Communigate. Pronto is a flash-based interface that has webmail and calendaring integrated into one interface. Not only is it one of the nicest webmail interfaces out there, but it also allows you to view your own calendar and view and share calendars with others in your company.

The Pronto Calendar
It also allows people to view their calendars in programs like Apple's iCal, which will update with the latest version of your online calendar anytime you refresh in iCal. Unfortunately, changes made in iCal don't go back, but at least this way, you can see what your online calendar has even when you're not on the Internet.

iCal Syncing
While it's not the "Exchange killer" that everyone's been looking for on the Mac, it's a great, low-cost solution for sharing calendaring with online access. Once released, it will simply be an add-on for all the users in a company for an additional small monthly cost per user.
If you're interested in testing it, please give us a holler at hosting@techsuperpowers.com. Keep in mind that to get the most out of it, you'll need a TSP hosting account already.
