Should I switch off Ustream's IRC server?

Questions like this have been coming into me more and more as of late. People are saying that they are seeing people leave ustream's IRC server (c.ustream.tv) in favor of other IRC networks (at the moment ones that can be used are iPocalypse, Wyldryde, AceIRC, and SummitIRC). People who advocate the switch say you have more control and options, but they also fail to consider somethings of importance.

1. Name confusion. When you side into ustream, you side into chat also. When you choose to switch servers, your users will not be sided into the new server when they sign into ustream. They will need to register with that server and then sign through nickserv. If a lot of your users use ustream's flash chat, this can cause some problems as the flash chat is not known for expecting other servers commands very well. Switching servers can also cause problems if the ustream nick a user uses is taken on the new server, for instance if Bob from ustream joined a wyldryde connected chat he would be switched to unidentified**** after a minute as that nick is registered on wyldryde.

2.Commands needed double. If you run on ustream's server there are a limited number of commands. People generally say this is why they switch, but for people who don't really have the time to invest into setting up a chat room on another server, the commands provided by ustream are more than enough. So if you plan on switching plan on learning a lot of new commands to run your chat.

3. Help is not provided by Ustream. When something goes wrong on ustream you know who to go to, ustream. If something goes wrong on another server do you know who to go to? If you have a problem with ustream you have to go to ustream, problem with chat you have to go to the chat server for help. Neither provides support for the other, causing problems.

There are other reasons to not move, but those are the biggest three to consider when making the decision. Personally my advice is if you are big into streaming and do it daily, and have the time to invest, then yes it is a benefit. But if you stream once or twice a week, and generally your chat isn't active outside of show times, you won't see much of a benefit.
