Sorry to jump in in the middle but I have done some testing using Selects from Views with Where clauses using pass-though queries in Access and, at least in that case, the filtering is done on the SQL Server and only the results are passed back to the client. The problem is you need to modify the SQL of the query to change the where clause. The way I tested this was to run the SQL Profiler on the Server and then open the query in Access. That way you can see exactly what the SQL Server is executing. I use Access to run reports against SQL Server and found this works pretty well. I also use stored procedures the same way if I need more complicated queries or need to manipulate the data for the reports.

The view pulls everything to the client, which then filters out everything not interesting. I could be wrong about this but it would be relatively easy to generate a test. Unfortunately, today I have lots of work on my plate, but by tomorrow I will have a 50M row table on which to test this hypothesis. A.
