This is interesting as I generally build a micro-sized dev version of  
some of my regular products, so I can develop firmware when I travel  
(very often).  It would be great to embed a programmer right onto  
these dev-boards, but it's a bummer that the 18F2550 is not available  
in SS packaging.  Do you know offhand if the firmware can be ported to  
any other 18F chip available in 28SSOP package?  I should download and  
experiment with the firmware.
