I have objects of a certain meta-type. They have some properties and one of the properties is a boolean. How do I make a dtml-in loop among those objects with the boolean set to yes?

I believe you have two choices: do if tests inside the dtml-in, or set up a ZCatalog with indexes for the relevant fields and use a catalog search call to retrieve the correct list of objects. That's still not easy if you want to do anything but an AND between the fields (see the Advanced ZCatalog Searching HowTo), but it should work. --RDM
