programming other Arduino boards using Arduino BT

Hi,

Is it possible to program Arduino boards using Arduino BT. I have purchased Arduino BT, Arduino pro mini, and Arduino lilypad. Also, is it possible to do the same for uploading bootloaders. I assume that all these boards come with a bootloader already uploaded but just in case you need to reload that again.

I'm just getting into this area and I made my first order. I'm asking because if there is away I wont need to place another order for the serial interface to program both the pro and the lillypad.

Thanks,
Tariq
