The issue is that in a cluster, you've got to make all those python
libraries available, and almost any way you do it is a headache, when
multiplied by 1024 nodes. Maybe, however, if the design in python is
straightforward enough, a C version won't be too bad to write.

I've done an awful lot of these "I/O mux" things in C, Python, Perl, ...  
while the interpretive languages always seem the best bet at first, issues
of diagnosis and fault tolerance have always led me back to C. Twisted is 
not the first such framework of its kind, it won't be the last, and they 
always lead to heartbreak. 

Python has other problems as well. Version skew issues are awful. We had a 
programming environment here for scientific users that would not behave 
correctly from mac->linux version, or even mac->mac versions! Hmm, isn't 
one of the arguments for Python a degree of portability?
