Hmm, interesting aproach.
If your basic requirement is to modify, remotley, the contents of an Access database, then you can use the remote features of adoanywhere browser/REX to modify the data.
But this would require you to instal REX on the server, if it is with an ISP they may refuse.
Both tools are currently free if you register at the adoanywhere forum
