Creating Tables On The Fly

I have an Access 2000 MDB with ODBC linked tables to a SQL Server 7 back
end. I currently have a selections table in the front end file which the
users use to make selections of records. The table has two fields -- primary
key (which matches primary key of main, SQL Server table), and a boolean
field. The table is linked to the main table in a heterogeneous inner join.

I'm looking to move the table to the back end, while still giving each
machine a unique set of selections. Using one large table with machine name
as part of the primary key actually slows things down. So I'm considering
using a series of tables, where each machine has its own table in the back
end for selections. The machine name would be incorporated in the particular
selections table name, and the front end link would be modified on the fly
when the database is opened to point to that machine's back end selections
table.

This would require having about 50-100 individual selections tables in the
back end database. Also, if a machine doesn't have a table when the database
is opened on that machine, then that table would be created on the fly,
populated, and pointed to via the ODBC link.

Anyone see any problems with this approach, specifically creating the table
on the fly and then immediately using it, as well as having that many little
tables running around? Thanks for any input!
