Sharing calendar info, certain categoris only?

[chopsxxx]

Does anyone know if there is an outlook addin or something that will allow one to only publish specific categories to an office online calendar? I'm pretty sure that publishing a calendar to Office Online that is on an Exchange server will be updated automatically when I add/change items on my PPC, and that is useful in itself.

But for instance: I have two jobs - IT support and musician. I want to publicly share my gig info with other musicians in order to advertise my availability for gigs, but I don't want people having my regular sched info.

I could just separate my gigs into another calendar in Outlook (desktop) and publish that, but I want to be able to do it from my handheld...

Anyone ever had to do the same?
