I contributed to the FreeSoC kickstart and received my boards recently but haven't had
time to try any interesting projects. Yes the native 5V operation and what seems to be 3x
22v10 equivalent PLD blocks allow for some interesting possibilities in creating slave bus
interfaces and/or DMA driven custom data pumps. The MFM emulator idea you've been
kicking around using SPI may get a lot simpler for example.
The 3s are a lot cheaper and I still have a soft spot for 8051s. Too bad they don't
have nearly the same RAM.
If you start working on something, let me know. I could probably help develop or test.

On a somewhat related(>) subject, has anyone used
the ARM-based Cypress PSoC chips? They're kind of interesting in having a standard
ARM core and a programmable logic part--and being able to use split power supplies to
support 5V I/O, for example.
Does anyone have any experience with these? They look to be a tad expensive.
