Does anyone know if there's a plug-in or something available to allow for OTR encryption in Spark? Or, failing that, perhaps it could be a feature request? 
Adium currently supports it, as well as my favorite client (aside from Spark), Mcabber. Oh, I think Pidgin does too. They all seem to work together quite nicely, providing all sorts of encrypted goodness. It would be really cool to add Spark to that list as well. Thanks!
