There was a ECC program from the previous century that worked as you 
described: the private key was derived solely from the user password. 
Unfortunately, I cannot recall its name (and I suspect it already 
vanished from the net since it was not secure due to its use of EC 
over binary composite field, Weil descent attack), but I guess someone 
here remembers its name, since at that time it was a rare example of 
ECC software.

Btw, this memorable private key technique has nothing to do with IBE, 
since no trusted third party is required.
