I've got kind of the same problem:
my apache/linux web site receives datas from clients via forms, datas I have to store in a Access format for future treatements (windows based).
So what I plan (planed) to do is to use an Access database on a windows machine on the network and use it to receive the sql orders.
One way to do this is to use unixODBC and an
ODBC-ODBC bridge,because it seems there's no Access odbc drivers under unix.
the problem is this bridge isn't free.

I'm actually trying to find a way to put
a network path into the connection sting...
I'm aware this probably isn't much help to you, (I hope my english is understandable)
if it may comfort you, I don't sleep much either...
