thanks!
no rush!... it was just one of those questions that popped into my head..
looked at the IDE a bit more.. and over 'thunk' it I guess..
just curious as to when I would ever 'choose' that option (Lilypad)
As far as the ATmegaBoot vs Optiloader..
(thats all a bit over my head)..
while I have loaded bootloaders using the IDE and Arduino as Programmer.. I have also used used the IDE and loaded Optiloader sketch and put Optiboot on some chips before as well
(did I phrase all correctly?) 
but to be honest I cant tell any difference or 'why' to use one over the other..
I dont believe I have ever done any 'EEPROM' writes in my code/projects yet..
(would that be to, for example, save some bits of data (locally in the chip) for when the power is gone...and to have it when power is restored/rebooted..etc)??
(if so,...I suppose I should go look it up, sounds useful)
thanks
