Reversed cause/consequence: these adapters are there because of 
investements in devices using RS232. When these devices disappear in 
favour of USB then no need anymore.

Microchip knows only about Windoze....

Wrong! All OS-s need drivers for serial ports (DOS came with none, so 
DOS communications programs needed to include some sort of driver).

Wrong! The device files contain info about memory size, but nothing 
about how to write code memory. And there are many differences between 
the PICs (one of the reasons we don't have a library to read/wrte code 
memory)! You might have a look at the firmware for the Wisp648 
programmer (written in Jal!) to understand that it is not as easy as you 
may think.

Wishfull thinking.
