I noticed the Guardian Project has developed a converter to move your off-the-record messaging keys between different IM applications. I'm curious what happens if your using multiple off-the-record messaging clients without using their otrfileconverter program. You must clearly verify each contact on each client and each contact must verify both your clients. Can you expect your contat's clients to remember both your two different keys once you've been verified twice? Is such behavior required by the standard?
