The main problem will be if your application uses "iterative queries" to update a screen. Each query will have a certain _long_ turnaround time. It is surprising how even a few of these accumulated delays impairs the applications responsiveness. This is a major problem with one of our sites, connected with a 2MB line, but with a ping time of 20-40 ms. Some of the complicated forms can use 4-5 sec for update. I actually get better response times with VNC (or another remote control program like PC-anywhere) running the application on a computer local to the server.
On the other hand _one_ query returning a few rows performs fine over a single channel ISDN.
