I have some suggestions on better alternatives to the web IRC clients you currently offer and also some quick criticism of the web IRC clients.
Flash needs to die in a fire already, this is a big community website in 2016 and not some GeoCities fansite in 2006, so a Flash based web IRC client doesn't sound like a good idea, both security-wise and preformance-wise. wsIRC is pretty fugly. These can both be replaced with Maid-IRC, which looks beautiful, matches Batoto's blue theme and is open source.
Mibbit looks pretty fugly as well and can be replaced with Kiwi IRC, which looks a lot better and is open source.
