I have modified my local copy of ZTopics to do what I need. Now I have an extra
checkbox that allows creation of 'parameterized' ZTopics. When it is checked,
caching is turned off and REQUEST is also looked up during construction of the
query at run time.

Does anyone else find this useful? I know this product is unsupported but is it
possible (or worth it) to submit this as a patch?
Are there other products that might achive the same (any kind of 'search
objects' or 'canned queries')?

Thanks,
