Yes, -frames is a per file option. I might add a -totframes option...

Oops, 10l cola goes to me.
I never tested the patch in 2 pass, so, good for pointing that out.
There are 3 possible solutions:
1. make -divx2pass a per file option, or even append to it a _1 automatically. 
Easy, but not the best.
2. make some vfctl to make MEncoder communicate with the ve after each file 
what frame we are up to. Possible, but hackish.
3. Find some way to uninit the video without uniniting the VE, and use that 
same VE for all the next files. Ideal, but hardest...
Anyone have a better suggestion?... I'm gonna try to do 3 for now

Hmm, what do you mean, do you mean something like this?

mencoder a.avi -ss 5 -frames 500 b.avi -ss 30 -frames 1000 ....

This was the design I intended all along for this.
