I would love to get hold of some for network

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).
