Still looking for that elusive filter

Still looking for a way to filter a DataSource on a date column in WSS 3.0. All the references I can find seem to make one or more of the following assumptions:

• You want to filter for items where the date is the current date, we're looking for 14 days ago


• You can write the code yourself in C# and upload it to the server, we're on a hosted service so cannot


• You are running MOSS (Microsoft Office Sharepoint Server), we're running WSS

I did find something that looked promising maybe using conditional formatting but it didn't work out.
