separating vicidial from asterisk

I've been thinking about separating vicidial from asterisk to help with potential load issues.
What snags, issues or other things I need to be aware of when doing this? Is it as simple as running the scratch install doc and adding the asterisk servers to the server table?
When recording happens, I guess it will occur locally on each asterisk server? And if so, I guess I would at least need to install the audio processing scripts on the asterisk servers, unless I use NFS?
I appreciate any insight from those who may be running them separately.
Thanks!
