Right now it looks like the ds30 bootloader will work with the 16F88 so I may end up with a nifty little, super economical development system for prototyping, testing PIC code and prototyping, testing shields. I'll be able to say a bit more once I get the XINO kit. There's a dearth of online documentation so all is possible until I get the hardware and documentation and reality sets in.

For working with the EM500/GA1000 (if the long-promised firmware is ever released) we only need a serial link and a reset line with very simple code since all the heavy lifting takes place in the EM500 (which requires coding in Tibbo's Basic dialect).

I think I can do a similar simple shield for the ConnectOne Socket LanReach and mini iWiFi modules (one only plugged in at a time).

Oh, one change to the layout. I've doubled the pads around the perimeter so a scope or logic probe can access pins which are not used on the shield but may be employed in the PIC program being developed for a more permanent design.
