Just noticed yesterday atleast one citatation direct from Cisco that they're 
going this route:

    Q. Do the Cisco Catalyst 3750 switches interoperate with SFPs from other 
       vendors?
    A. No, like other Cisco switches and routers, the Cisco Catalyst 3750 
       switches  do not interoperate with other vendors SFPs. The switch will
       shut down the port if an SFP is inserted that is not a Cisco SFP.
