I don't have the answers you're looking for here, but this has been my experiance:

1. Speed: I am converting applications from IBM DB/2-Query Manager applications running on desktop 486s to SQL Server/VFP applications using ODBC and TCP/IP. The VFP/SQL Server applications are much, much faster. How the speed compares to other types of applications I do not know. Using parametized views helps.
2. It should work with Oracle, SQL Server, VFP databases, etc. Just change the connection to point to the correct backend. There are some issues such as in SQL Server there is no date only field type, its a datatime field type. So in my remote views that have date fields I have to change the properties to change the field type from datetime to date.
