It would be great if I could just pick a few contexts to sync to iCal.

If I have access to my iCal, chances are, I'm at my laptop. If I'm at my laptop, I don't need the actions listed in iCal because I have access to OmniFocus.

When I'm not at my computer, I have my Treo, and I do need actions listed in my Treo. I need @Phone, @Phone–BusinessHours, @Errands, @Errands–Location1, @Errands–Location2, @Errands–Location3, @Home-FixIt, @Home–Backyard, etc.

When I'm on my Treo only, and not my laptop, I don't need access to @Laptop, @Laptop–ParrallelsXPOpen, @Laptop–Quicken, @Laptop–wScanneror @Laptop-wPaperFiles.

Treo syncing is cumbersome, and there are a limited number of Treo "categories" I don't want these other contexts to map to the Treo because they use up those precious categories, so I don't sync them.

But if I'm not syncing them into the Treo via iCal, I don't want them in iCal at all. 1) It slows down the OmniFocus–iCal sync, 2) It slows down sync services, 3) It slows down my iCal, 4) It clogs up my iCal screen real estate and hiding them takes work, 5) It clogs up my Treo Missing Sync Utility and choosing what to sync takes work, 6) it's more crap in my user folder that needs to be backed up.
