If you're pulling that deleted tag data over the wire, then no. If you're going to have a local machine process local data then yes. If you're going to have a server remotely process queries and return data, then yes.
I believe in VFP9 you can now INDEX ON DELETED() FOR DELETED() TAG IXDELETED BINARY (REMEMBER NOT TO USE KEYWORDS)
That means the amount of data flow from the server to the pc on the LAN goes way down, so you could potentially use that too and have the deleted tag all the time.
