What capacity needed for client-server connection? (OpenInsight Specific)

We have a possible client at a small museum with ties to a larger institution some distance away. They plan to connect the two sites and install our app at an NT server at the main institution. With the database at the main institution's server, backup procedures will be easier and backups more reliable. The database will also contain images (in separate files), so there's also the matter of disk space being more available on the server than locally.
Now we/they need to know what capacity is needed for the connection. So far we must assume there's a fair chance they cannot afford any networking product. I know that even on a normal LAN OIWG app performance suffers without a networking product, but they accept that. The question is how much more you're penalised if you run it over e.g a 64Kbit ISDN connection.
They do not yet know if there'll be a single user or several users, but there will be relatively few users (1-3). All the users will be at the museum as far as plans go today. But I guess the bottleneck is the museum-main connection, and that adding additional users at the main institution's LAN will be no problem, so it's the number of users at the museum that counts.
In addition to the database data there *might* be 20-50-100KB JPG images going back and forth (scanned locally, and stored at and retrieved from the server), but here the specs and needs aren't decided yet).
All input on this will be appreciated.

I assume you are using some type of dial-up networking. If you try to run the remote oinsight.exe it will probably be too slow. The best way to do this might be to have the application software local to the remote machines hard drive (ie. oengine, etc.) but check the licensing of this. Then have your app's .dbt file pointing to the remote data. This way, only the data will have to travel accross the dail-up (64K) line. This works reasonably well with AREV but I havn't tried it with OI.
If you wait for JRev, this will definitly solve your problem.
