Simple Solution, if you use the programming lines (and they are outputs 
with a high impedance load, or inputs with a high impedance source) then 
solder the chips on, take a spare PCB (or make one) drill the holes out 
to suit some pointed bed of nails probes, and then just put the PCB's 
with just the CPU (xtal and caps) on the bed of nails and program away, 
it is how I do tight designs where I can not get space for a connector 
(I just leave so sacrificial pads on the bottom or top for programming)

Regards,

Kat.
