It is possible to eliminate frequent writes to the USB drive. I think the 'live' distributions that run off the CD must be doing that, as CD is readonly.For a simple starter I will see if I can use something like ramfs to achieve this.
Thanks for the suggestions on this line.

I heard of people building usb-bootable version of some
(live)distributions, and that they had to deal with similar issues.
Maybe it's worth looking at them how they solve this issue.
Sorry for not having a link at hand, I just remember something like
that.

What is "not long"?
If it's only a month, that's probably enough! That's a cool tool, if you
use it daily, spending 20Dollars/Euros each month for a new USB stick is
not exactly a lot compared the usefullness of that tool.
The same technology could probably applied to 2.5" usb harddisk, making
it slightly bigger, but still possible to have your complete desktop in
a shirt's pocket.
