You would still be  putting a read lock on Paradox tables from an 
external program. The same would apply to Access tables. Access has only 
page locks, not record locks, so your read locks on a whole page could 
break it.

My only suggestion is to try it and see, after warning your user it's a 
bad idea and it could cause intermittent problems that require 
rebuilding an reorganising tables and/or access databases. Who knows? 
Depending on the workflows and traffic, you may have no problems at all.

In the best of all worlds, you would combine both databases in a SQL 
Server database and have Paradox and Access use the same database. No 
problem at all.

As Steven said, it's a bad idea.
