Interesting.
In 4thed, we have been told:
charecter level=power level
And that this will apply to spells, so there will be spells up to level 30.
There has been at least one thread on the 4thed forum on how Monte had been thinking about/doing something similar.
NOW, he migth publish his own version of this, even with 4th ed coming out. And he is running a home campaing with a bunch of other mechanics which have a 4thish feel. And he could also do something based on those...
