[Pvfs2-developers] host id

[Nicholas Mills]

I would like to use the string but Dr. Ligon wanted to avoid using a string.
I assume it's because they have a variable length. We're going to need to
send this across the network.

If we were going to use a string would it be better to allocate it
dynamically or use a fixed-size buffer (something like 1024 bytes)?
