Network Tables Rev. 2.0 Questions

[William Kunkel]

Hi! I was reading the Network Tables Protocol Specification (Revision 2.0), and I have a few questions about things that seem vague or missing from the document, if anyone could possibly answer them.

1. Once an entry is created, can it be removed, or does it persist for the life of the server?
2. If a server sends an Entry Assignment message to a client whose local network table already contains the ID, what is the client expected to do? Drop the request? Replace the existing entry?
3. Can the length of arrays of values change?
4. Is there a maximum length to arrays?

Thanks a bunch!
