You don’t have to install all of the full SQL Server client tools to get connectivity to SQL Server or analysis services. They have been broken up and are available individually for download as part of the SQL Server feature pack.
For example you can pull down:
X86 Package (sqlncli.msi) - 4549 KB X64 Package (sqlncli.msi) - 7963 KB IA64 Package (sqlncli.msi) - 11112 KB
X86 Package(SQLServer2008_ASOLEDB10.msi) - 19490 KB X64 Package (SQLServer2008_ASOLEDB10.msi) - 43945 KB IA64 Package(SQLServer2008_ASOLEDB10.msi) - 50682 KB
X86 Package(SQLSERVER2008_ASAMO10.msi) - 2659 KB X64 Package (SQLSERVER2008_ASAMO10.msi) - 4317 KB IA64 Package(SQLSERVER2008_ASAMO10.msi) - 6055 KB
There’s also a load of other utilities like backward compatibility stuff e.g. to edit and run data transformation services packages.
Finally as I have blogged before these tools are not licensed in themselves, it is SQL Server that is licensed for either client access or per cpu (socket NOT core).
