O.K., that basically answers my question. Functionally, the FTDI Multi-Protocol Synchronous Serial Engine (MPSSE) operation is very similar to USB Blaster operation, except for a higher repeat count with MPSSE and more compact commands with USB Blaster. But I expect, that the throughput isn't much diferent, because both are using a 6 MHz TCK. Also USB Blaster has additional commands to send AS programming data, this wouldn't work with an FTDI chip without changing the hardware connection.
