The private line should be more reliable and less subject to line noise.

You will have a speed problem since all the records you are working with will have to travel over the phone line. You can minimize problems by making sure your queries are fully Rushmore optimizable. If they are not all the records will pass over the phone line to see if they belong in the result set, but with Rushmore only the index data must be examined and only the records in the result set will be transfered.

You may want to consider using a product like PC-Anywhere to access the computer running the application. This avoids having to transfer the data over the phone line but you will still experience response problems with screen updates.
