Oh please. Every day researchers nibble at the details of biology. It is the dream of every researcher to upset the applecart. If ID was a real scientific idea, it would suggest reseach that could upset the applecart.
Quantum theory was a case of a major upset, but if you look at the history, the data that lead to the quantum idea came before the idea. There is [are?] no such data gnawing at evolution.
If you expect to replace evolution with a new theory, first you will need to find something evolution can't explain, not just something that is unknown, but something that contradicts evolution.
Right now you have some structures that are unexplained in detail, but they are typical of the difficult problems in biology, not contradictions. That's it. that all ID has. Some unexplained phenomena. Period.
That is contrary to your first statement "anyone really familiar with the subject does not question evolution" - it is impossible to nibble at the details of something you do not even question.
