Of course it has the chicken and egg problem:
---------------------
How to program the main micro the first time?
This is an interesting problem: a new device can't work as programmer, so
it must be programmed in some way. Apart from asking someone else to do
it for you, my advice is to build one of those serial programmers, like
JDM, to do the job the first time. It would be a good idea to buy a backup
micro, in order to program it with updated firmware versions.
---------------------
As you have to build a programmer to build a programmer?
And most JDM style programmers won't work on modern serial hardware.
It's a real problem.
