Using the FTDI as a burnloader(Not a Question!)

I found i my electronics magazine an article 'bout Arduino, and i saw a link to site howto burn a bootloader on your arduino using the Bit-Bang function of the FTDI. Maybe you all wanted to know this. But all the Credit goes to Mr. Suz
here's the link: http://www.geocities.jp/arduino_diecimila/bootloader/index_en.html

PS: how many times can you rewrite a bootloader? and works the flash just like a usb-drive or has this also a limitation?

That method has been around for a little while and it works nicely.
According to the datasheet a 168's flash can be programmed >10,000 times and its EEPROM >100,000 times.

So you can burn a bootloader more times than a sketch? That, i think doesn't make sense. And, can i also burn bootloaders on other chips this way like the ATTiny-45?

No it doesn't make sense, because it's not accurate. The sketch and the bootloader are both stored in the same type of memory--flash, not EEPROM--so they both have the same limits, not different.
