Quick question: I've read your nice tutorial with great interest. But I did not find any discussion relating to practical bandwidth. On a DE0-nano board, would this avalon/usb blaster interface support an average rate of 2 MB/s from board to host?

Sure, I've got lots of documents ...
https://www.ovro.caltech.edu/~dwh/correlator/cobra_docs.html The JTAG interface performance is documented in altera_jtag_to_avalon_analysis.pdf The performance is only about 600kB/s.
You can use an FTDI device, check out ftdi.pdf (60MB/s for their HS devices) and ftdi_spi.pdf (2MB/s = 16Mbps serial data rate ... might be a bit fast).
Take a read of those docs, and ask questions.
Cheers,
