Daniel: I greatly appreciate the suggestion: it seems like it might offer just what i'm looking for. But i'm having a bit of trouble getting things set up (the dreaded "no results" on my simple test case, which means i'm still missing something).
Do you happen to have a pointer to a running site that i can compare to, so your end results can encourage me to persevere?
