A lot of phones already support SyncML, which synchronizes the phone calendar with a desktop or online calendar, but it's not the answer. The fact is most people are subscribed to more than 1 calendar, and most clients don't let you do a partial sync. For example say you want to create an event for your friends calendar but not to share it with your Work calendar.
A simpler solution is to run a CalDAV client on your cellphone. That would allow you to view and edit remote calendars via the HTTP WebDAV protocol. Mozilla Sunbird uses the same approach for sharing, and there are a number of oss calendar servers out there. What we really need now is an open source version for the cellphone, using either java or wap. Let me know at mchiu77 at gmail dot com, if you are also interested in the idea.
The big problem with SIMPLE is that Microsoft has hijacked the standard and added their own proprietary extensions to LCS. I haven't heard much about IBM's Sametime, but I am guessing its not so popular.
Now that Microsoft and Yahoo have agreed to link their networks, they can afford to hold out on integration with others for another 3-5 years.
