Funny, I read that totally differently: my reading is that if you
start with LGPL you cannot move to commercial licensing, but if you
start with commercial, I do not see how this would prevent you
from going LGPL, which incidentally was what the OP was contemplating.

And yes commercial is very vague term here LGPL can be commercial surely,
(L)GPL is about freedom not money as we all know.

This whole sentence (above) has a very home spun feeling to it, not very
professional IMHO, unlike the LGPL which is carefully worded even in the
things it leaves ambiguous, on purpose I guess.
