That would be interesting.

As long as you can make everything fixed length and avoid branching (use 
predication) I think it could be done quite efficiently on the GPU. e.g. 
buffer up say 100K packets and run a kernel function over a whole batch, 
reducing the batch size and submission frequency based on network traffic.

Deep packet inspection may be harder although not impossible (note this 
is pre-cuda but same concepts apply):

Luckily Fermi can handle 32 bit integers (previous GT200 could only do 
24bit integers which would make packet stuff harder - 32 bit integers 
are available in CUDA but are emulated and slow on previous gen nvidia 
GPUs).

Anyone else on the list playing with CUDA? (i'd be keen to share 
experiences).
