Hi Wasim,
  I've posted a 256-bond-per-atom test build for you here.
Please try it, and let me know if that resolves your max bond count
problem or not:
  http://www.ks.uiuc.edu/Research/vmd/alpha/256bonds/vmd-1.9.4a34.bin.LINUXAMD64.opengl.tar.gz

It may be possible to eliminate the compile-time limited maximum bond count
in the future, but I'll have to look closely at the practicality and
invasiveness of the required changes and their performance cost to determine
whether I'm willing to do the necessary rearchitecture in VMD.

Best,
  John Stone
