Audio+lcd Expansion board
I'd like to see an audio expansion board with the LCD controller pins available for use. That would make audio applications much more flexible.

On the AudioStix2 it would be nice to expose a few more signals
Specifically, I'm looking for the audio in/out left/right/gnd and VBATT signals exposed on pin headers. This would make it easier to make daughter cards that connect via the SIP headers and provide these functions via alternate connectors.

How about a buddy board with an audio in/audio out connector linked to the PXA AC97 function?
done: with our audiostix expansion board.

FPGA for HW encryption, OGG/MP3 decoding, etc
Could all become possible over time using expansion board with a FPGA, so that various tasks can be accelerated (first thing which comes to mind is encryption (VPN), second is audio/video decoding) Opencores has a wealth of stuff which can be used, Gumstixers with a FPGA can use it to enhance several stuff. Additionally, if the conversations with the OGP people are fruitful, the FPGA could be the foundation for the Screen module for the PDA above.

//coment by 'thebrain' this could also tie in with robotics.

// I don't see an FPGA helping with Ogg encoding. Ogg and MP3 decoding should already be possible in software. Ogg encoding (with the current encoder) needs floating point arithmetic. It would be great to have a processor with an FPU, but that probably means abandoning the ARM/XSCale unless Intel changes their approach. --phr

A FPU wouldn't help with Vorbis decoding, there already is an all integer decoder called Tremor designed especially for ARM-based platforms, such as the iPod. -- DiabloD3
