I understand your point, there's two problems with most of the terminal emulators I've seen:

  - they are either poorly or completely unsupported  
  - the code is a nightmare, badly written, undocumented

Both make extending a VTE an almost impossible task. Actually, that's why we (at Selectel) wrote `pyte` [http://github.com/selectel/pyte], which soon became open-source.

As for speed issues, have you considered implementing incremental updates (like in AnyTerm, for example)? This approach works perfectly in our setup (multiple clients, multiple terminals).

P. S. Looking through the code, I can tell that you had some tough nights throughout those 9 months :) Good job!
