Your first paragraph completely disappears without the callbacks. The clients that are up send data. The others don't. Period. No callbacks, no checking, no Hashtable. If the server has a list of all expected clients, or notices that a past client hasn't sent for a while, it can raise some kind of alert, if your system needs that.
The performance of the second paragraph is entirely up to you, by setting the retry interval.
