It would be nice, but if no graphic i/f is used for the server side, I 
think it would be better to implement it in standard C instead of PyQt, 
for portability reasons, so the server could be easily rebuilt for 
running in a non-PC class embedded linux computer (like those using ARM)

For providing ntp, probably the best way is to use ntp :) As far as I 
remember, since I've not played around it since some time, the LinuxPPS 
driver is implemented as a character driver, so several applications can 
read it, and as other has pointed, ntp i/f to the GPS can be implemented 
using shmem. ntp can also be recompiled for running in almost anything 
(I've put it into work both in Nios-II uClinux-MMU and Blackfin 
uClinux-nonMMU, also taking time from an M12 using Linux-PPS)

Best regards,
