Also there were some experiments with 'overclocking' SPI bus connecting wi-fi chip to main CPU. So far it is unstable but there is some potential.
Well, I'm currently using 'overclocked' wlan driver with Nokia 770 (divisor set to 3, one step down from unreliable settings), openssh is configured to use 'arcfour' encryption (yes, I know it has a security flaw). Nokia 770 filesystem is mounted with sshfs on my desktop PC and I use it to move files to the device. It works perfectly and provides speed ~570KB/s. So I have no need for USB anymore Hopefully wlan speed can be improved further.

OMAP1710 should have hardware acceleration for DES/3DES. I wonder if it would be possible/realistic to patch kernel and openssh to use it?
