SDHC high capacity flash working
Checked out an 8GB SDHC card and it is working without issue.

Formatting it FAT32 (for compatibility) eats 400MB.
I bought the card for $21 shipped.
Typical home would use 6-10 Digispeakers, that's 80GB storage capacity. All of it fast and silent. 16GB ($48) cards work too. I see a 32GB one for $130 now.
The cards are user installable. In three years 32GB cards will be $20. Prices on these cards are going way down due to their use in camcorders.
I'm still sorting out the interrupt handlers for IR. I hope to get it working soon.
