It seems that classical things is more useful...
Can Maxwell explain what's light speed in photon frame?
No, but quantum field theory probably does

Since, by the Lorenz formulas, any measurement in the direction of motion or any measurement of time is 0, a photon has no "frame of reference".

Talking v < c

@Hallsofivy:
Good question. Below is some suggestions.
1. Read benit's previous reply about the relation between light speed and SR. It's interesting.
2. Read the thread "what's the secret behind v < c ? "
3. I read an article of a famous scientist. he trys to calculate the light speed in photon frame. His mathematical method is a bit complicated. His result is c. The article also tells that Einstein spent 10 plus years to think about this question. The thread is in guokr.com. It's "当你与光子同速并飞, 你看光子的速度是0还是光速?"

A. When I was in school, I discovered an interesting phenominon: different students might use different methods to solve an equation, but their solutions are the same. Sometimes people have to admire the elegance and magic of math which is created by man.
.............
B. Anyone theory is limited ability.
